Can a pentagon have three right angles and if not or if so explain why?
Yes it can. Imagine a square with the corner cut off. The remaining shape is a pentagon with three right angles.
Is there a pentagon with a right angle?
Strictly speaking a pentagon is a plane figure with five straight sides and five angles, so yes, a pentagon can have one - or more - right angles. Imagine a rectangle with one of the corners cut off - that would have five sides and three right angles. .......... ............. ................ .................. .................. .................. ..................
What is the function of the set square?
It's primarily a template for drawing lines at accurate right-angles and other angles to a line, usually 30º / 60º and 45º for standard set-squares. It's also used for drawing parallel lines. Adjustable set-squares allow you to set off other angles.

Why are multiple images formed when two mirrors are placed at right angles to each other?
With two mirrors at right angles you will have 3 (360/90 - 1) images of an object. Two of these are primary and the third is secondary. Some light rays from the object bounce of each of the mirrors to your eye to form the two primary images. But there are other rays that bounce off a mirror onto the second mirror before they get to you. This produced the secondary image.
Use of right angles in real world?

What is the greatest number that can be rounded off to 90?

Do trapezoids have right angles?
No, trapezoids do not have right angles. A trapezoid is a quadrilateral with only one pair of parallel sides. The other two non-parallel sides can be of different lengths and angles.

What is a polygon that has 2 right angles and is not a quadrilateral?
Any non-regular polygon from pentagon and up can have two or more right angles. Take a square and chop off the top and then make a two more connecting line segments (like a house with roof), and you have an irregular pentagon with 2 right angles at the bottom, for example.

Is a rhombus with no right angles never a square?
That is correct. A square, by definition, has four right angles. (I remember back at junior school for being told off for creating an 'irregular square' because the angles weren't accurate!) I think (somebody may correct me) that in a rhombus, each set of two corners must match with their angles, anything else is a quadrilateral.
Can a triangle have at most one right angle or acute angle?
Only one right angle but up to 3 acute angles (think of an equilateral triangle, all angles are 60 degrees). On a non-flat surface all bets are off!
