What is the sum of interior angles of a right trapizoid?
a triangle= 180' and so try to see how many angles u can touch to make triangle(s) in a trapizoid say u fit 3 then u do 180x3
How many right angles are on the letter H?
Looks like 4 where the horizontal bar meets the vertical bars.
Is every rhombus a square?
No. A rhombus, in general, has a pair of acute angles opposite one another, and a pair of obtuse angles. It is only as a special case that all four angles are right angles and so the rhombus becomes a square.So every rhombus is NOT a square but every square is a special type of rhombus.
Why are right angles used in construction?
Right angles are equal to 90 degrees; making it completely straight. They are used in constructions so the builder can see if the building is completely straight (vertically). If the building is not 90 degrees, it is likely to collapse.
How can you tell if three numbers equal a right triangle?
A right triangle is a triangle that has one 90 degree angle, and 2 other angles. Some special ones are 45-45-90, and 30-60-90. The sum of the angles in a triangle will always = 180 degrees. Since we know a triangle has 3 angles, and in particular, a right triangle has a 90 degree angle. We can say 180 degrees - 90 degrees = the other 2 angles. Add the other 2 angles in your triangle. Usually one is given as 90 degrees, or has a small square mark in the corner of the triangle to indicate that it is a right triangle. Once you add the other 2 angles, see if they add up to 90 degrees. If they do, you have a right triangle. If they do not, you either do not have a right triangle OR your triangle is broken and all 3 angles do not add up to 180 degrees.
