Question

Construct a right triangle whose two sides containing the right angle measure 9 cm and
12 cm.​

Answer 1

Answer:

First draw a line of 9cm then mark right angle with compass or protractor. I have constructed with compass. Then draw 12cm line from right angle. By Pythagoros Theorem 15cm will be the hypotenuse.

${h }^{2} = {b }^{2} + {p}^{2}$

${h}^{2} = {9}^{2} + {12}^{2}$

${h}^{2} = 81 + 144$

${h}^{2} = 225 \\ \ {h }^{2} = \sqrt{225}$

$h = 15cm$

15cm will be the hypotenuse.
