A right angle triangle must have a 90 degree angle and two acute angles.
An acute angle is an angle of a shape under 90 degrees, an angle over 90 degrees is called an obtuse angle. hope this helps!:D
A Right Isosceles Triangle is a shape that has one 90° angle. 90 degrees + the other two angles add up to 180 degrees.
It is a right angle
A right angle triangle. (if it is a triangle)
A right angle triangle.

A square, A rectangle
The sum of an angle and its complement is 90 degrees. So the unknown angle must be 90 - 75 = 15 degrees.
L shape
