These textbook solutions will support you in understanding the application of the basic proportionality theorem to solve Class 10 problems based on triangles. To further practise these rules, you can explore the concept videos, topic notes, practice tests and other resources on our e-learning portal.
We also have an UnDoubt Ask an Expert platform to give you access to expert assistance to resolve doubts. Let AD and PS be the medians of these triangles. Given that sides are 7 cm, 24 cm, and 25 cm. Squaring the lengths of these sides we get 49, , and Therefore, given triangle is satisfying Pythagoras theorem.
So, it is a right triangle. The longest side in a right angled triangle is the hypotenuse. Given that sides are 3 cm, 8 cm, and 6 cm. Squaring the lengths of these sides we may get 9, 64, and Clearly, sum of squares of lengths of two sides is not equal to square of length of third side.
Therefore given triangle is not satisfying Pythagoras theorem. So, it is not a right triangle iii. Given that sides are 50 cm, 80 cm, and cm. Squaring the lengths of these sides we may get , , and So, it is not a right triangle. Given that sides are 13 cm, 12 cm, and 5 cm. Therefore given triangle is satisfying Pythagoras theorem.
Let us join DB. Let AB be the height of tip of fishing rod from water surface. Let BC be the horizontal distance of fly from the tip of fishing rod. Then, AC is the length of string.

Chapter 6 - Triangles Exercise Ex. Two squares with sides 1 cm and 2 cm ii Trapezium and Square Triangle and Parallelogram.
Median divides opposite side. Let ABCD be a square of side a. So, all equilateral triangles are similar to each other. So, ratio between areas of these triangles will be equal to the square of the ratio between sides of these triangles. If, two triangles are similar to each other, ratio between areas of these triangles will be equal to the square of the ratio between sides of these triangles.
Given that sides are in the Byjus Maths Class 9 Triangles Ltd ratio Hence, d. Given that ABC is an isosceles triangle. We know that altitude bisects the opposite side. So, length of each altitude will be. Let OB be the pole and AB be the wire. Therefore by Pythagoras theorem,. Let these distances are represented by OA and OB respectively. Now applying Pythagoras theorem. Let CD and AB be the poles of height 11 and 6 m. In ACE,. Let side of equilateral triangle be a. Hence, c. MD iii. AB - 2DC. Now, she pulls string at rate of 5 cm per second.
