Question

find the measure of each of the two equal angles of an isosceles right angled triangle

Answer 1

isosceles triangle;- Having two sides and two angles equal.
Let the angle be X

x+x+90=180
x=45
I,e.

one angle is 90 and the other two angles are 45

Answer 2

ANSWER:

Sum of all angles in a triangle in always 180 degree.
✏So, first is 90 degree as it is right angled triangle.
✏Let the equal angles be ' x'

Therefore:-

$90 +x + x \: = 180$
$= \: 90 + 2x = \: 180$
$= 2x = \: 180 - 90 = 90$
$therefore \: x = 90 \div 2 = 45$

Since the measure of equal angles is 45 degree.
Hope it'll help you.
