A quadrilateral can only have either 2 right angles or four. As you may (or may not) know, the angles in a quadrilateral must add up to 360 degrees. If you have 3 right angles that adds up to 270 degrees, so the last side must also be 90 degrees.

Why cant a rectangle be a trapezoid?
A rectangle has four right angles; a trapezoid doesn't.
How do you draw a pentagon with four right angles?
you cant because it would be a square
Why cant a right triangle be an equilateral?
An equilateral triangle can't be a right triangle since an equilateral triangle has all 60° angles, which are NOT right angles [measuring 90°]. If a triangle is a right triangle, then it has a right angle!
When all angle in a triangle measure axactly 90 degrees?
It cant be possible because a triangle only consists of 180 degree angles !! As 90 + 90 = 180 thus 2 or more than 2 angles in a triangle cant be right angles i.e. 90 degree :D
Why cant there be a obtuse angle in a right triagle?
A triangles angles must add up to 180 degrees, no more or less
Can a quadrilateral have 4 angles with a different measure?
No. It can so on your paper you cant put it cant have 4 angels with a different measure
How many obtuse angles can a quadrilateral have?
3 you cant draw one with four
Why cant a rectangle be a trapezoid?

Your lengths cant be measured when 2 of us meet you form right angles?
It is perpendicular lines
Why cant a right triangle be an equilateral?
An equilateral triangle can't be a right triangle since an equilateral triangle has all 60° angles, which are NOT right angles [measuring 90°]. If a triangle is a right triangle, then it has a right angle!
Can a quadrilateral be curved?
no, a quadrilateral cant be curved because it is a closed STRAIGHT sided figure with four sides...
Can a trapezoid be drawn with 3 right angle?
a trapezoid has no right angles whatsoever. no they cant because trapezoids have only 4 sides and dented
How is geomerty used in the real world?
without geometry, we cant build a house in a right manner because, we need to now the angles and the right measurements....
When all angle in a triangle measure axactly 90 degrees?
It cant be possible because a triangle only consists of 180 degree angles !! As 90 + 90 = 180 thus 2 or more than 2 angles in a triangle cant be right angles i.e. 90 degree :D
Why cant there be a obtuse angle in a right triagle?
A triangles angles must add up to 180 degrees, no more or less
Why cant an equilateral triangle have a right angle?
eqilateral triangle has 3 equal angles.by asp , sum of angles is 180, thus, angles are 180/3=60 degree each
