According to the Pythagoras theorem the square of hypotenuse is equal to the sum of squares of base and perpendicular.

Hypotenues

H

Consider;

Base = 9

Perpendicular = 12

Then hypotenuse is ;

H

H

H = 15

The perimeter of a right angle triangle is equal to the sum of measure of hypotenuse, perpendicular and base.

Perimeter of right angle triangle= hypotenuse + base + perpendicular

Perimeter of right angle triangle= 15 + 9 + 12

Perimeter of right angle triangle= 36

Hypotenues

^{2}= base^{2}+ perpendicular^{2}H

^{2}= B^{2}+ P^{2}Consider;

Base = 9

Perpendicular = 12

Then hypotenuse is ;

H

^{2}= 9^{2}+ 12^{2}H

^{2}= 81 + 144H

^{2}= 225H = 15

The perimeter of a right angle triangle is equal to the sum of measure of hypotenuse, perpendicular and base.

Perimeter of right angle triangle= hypotenuse + base + perpendicular

Perimeter of right angle triangle= 15 + 9 + 12

Perimeter of right angle triangle= 36
