Hey there! We receieved your request. Class 10 maths ch triangles 40 point of intersection of the medians of the three sides of the Triangle is trianlges centroid cn that Triangle. It will always inside the Triangle. The point of intersection of the angle bisectors of the three angles of the Triangle is called the incenter of that Triangle.
It is the point from where Class 10 Maths Ch Triangles 15 the circle is inscribed in the Triangle. The radius is find by drawing the perpendicular from the incenter to any of the side of the Triangle.
The point of intersection of the perpendicular bisectors of the three vertices of the Triangle is called the circumcenter of that Triangle. It is not always inside the Triangle. It could be outside the Triangle for obtuse Triangle and fall at the midpoint of the hypotenuse of the right angled Triangle. The point of intersection of the altitudes of the Triangle is the orthocenter math that Triangle. Like circumcenterclaass also falls outside the Triangle in class 10 maths ch triangles 40 of obtuse Triangle and it falls at the vertex of the Triangle in case of right angle Triangle.
The above explanation shows that if two figures are congruent then they will be similar also but it is not necessary that if two figures are similar then they will be congruent. If the corresponding angles of the two Triangles are same then they are called equiangular Triangles. According to Thales theoremif in a given Triangle a line is drawn parallel to any of the sides of the Triangle so that the other two sides intersect at some distinct point then it divides the two sides in the same ratio.
It is the opposite of basic proportionality theorem, which says that if in a given Triangle a straight line divides the two sides of the Triangle in the same ratio then that straight line is parallel to the matbs side of the Triangle. If in two given Class 10 maths ch triangles 40 all the corresponding angles are equal then their corresponding sides will also be in proportion.
Remark : If triangled two xh angles of the two Triangles are equal then according to the sum of angles of Triangle, the troangles angle will also be equal. So trisngles Triangles will be similar if their two angles are equal with the two angles of another Triangle.
This is known as AA Angle-Angle criteria. If in the two Triangles, all the sides of one Triangle cass in same ratio with the corresponding sides of the other Triangle, then their corresponding angles will be equal. Hence the two Triangles are similar. Remark : The above two criterions shows that if any of the two criteria satisfies then the other implies.
So we need not check for both the conditions to satisfy mmaths find the similarity of the two Triangles. If all the angles are equal then all the sides will be in proportion itself and vice versa. If in the two Triangles, two sides are in the same ratio with the two sides of the other Triangle and the angle including those sides is equal then these two Triangles will be similar.
If the two similar Triangles are given then the square of the ratio of their class 10 maths ch triangles 40 sides will be equal griangles the ratio of their area. Pythagoras theorem says that in a right angle Triangle, the square of the hypotenuse i. In a Triangle, if the sum of the square of the two sides is equal to the square trianngles the third side then the given Triangle is a right angle Triangle.
In a right angle Triangle, if we draw a perpendicular from the trianglex angle to the hypotenuse of the Triangle, then both the new Triangles triwngles be similar to the whole Triangle. The laws of sines and cosines are used to find the unknown side or angle of an oblique Triangle. Oligue Triangle is a Triangle which is not a right angle Triangle. The law of sines shows that the sides of a Triangle are proportional to class 10 maths ch triangles 40 sines of the opposite angles.

Revision Notes on Triangles Any polygon which has three sides and three vertices is known as Triangle. Types of Triangles 1. There are three types of Triangles on the basis of the length of the sides. There are three types of Triangles on the basis of angles. Centers of the Triangle There are four different centers of hriangles Triangle 1.
Class 10 maths ch triangles 40 of a Triangle The point of intersection of the medians of the three sides of the Triangle is the centroid of that Triangle. Incenter of a Triangle The point of intersection of the angle bisectors of the three angles of the Triangle is called the incenter of that Triangle.
Circumcenter of the Triangle The point of intersection of the perpendicular bisectors of the three vertices of the Triangle is called the circumcenter of that Triangle. Orthocenter The point of intersection of the altitudes of the Triangle is the orthocenter of that Triangle. Congruent vs. Similar figures Congruent Similar Angles Corresponding angles are.
Corresponding angles are. Sides Corresponding sides are. Corresponding sides are proportional. Example Explanation Both the square have the same angles and same. Both the squares have same angles but not the same sides. Symbols The above explanation shows that if two figures are congruent class 10 maths ch triangles 40 they will be similar also but tirangles is not necessary that if two triangels are similar then they will be congruent.
Similarity of Triangles In the Triangles class 10 maths ch triangles 40 we will use the same condition that the two Triangles will be similar if- The corresponding angles of the two Triangles are same and The corresponding sides of the two Triangles are in same proportion. Basic Proportionality Theorem Thales Theorem According to Thales theoremif in a given Triangle a line is drawn parallel to any of the sides of the Triangle so that the other two sides intersect at some distinct point then it divides the two sides in mmaths same ratio.
