Question

if one angle of a right angled triangle is 45 degree then the measure of the third angle is

Answer 1

other angle is 45°
by using property that sum of angles of a triangle is 180°
therefore the other angle is 45°

Answer 2

In the right triangle, 2 angles measure 90° and 45°
So, using angle sum property, the third angle is 180°-(90+45)° = 45°
