Question

Which of the following types of polygons do not exist?

(i) right triangles
(ii) with right angles
(iii) with all acute angles

Answer 1

I assume by (ii)with right angles,you mean a triangle which has more that one right angle.If so that is the answer.

Answer 2

CORRECTION: (i) EQUILATERAL right triangles
(ii) TRAPEZOIDS with right angles
(iii)RHOMBI with all acute angles

Answer 3

Well here the answer is definitely (i)

Answer 4

thanks, but PLEASE explain

Answer 5

It says it is an equilateral right triangle.A right triangle means there must be a right angle and an equilateral triangle means all angles must be equal.So an equilateral right triangle means a triangle with all 3 angles as 90 degrees.Imagine that!Sum of angles in a triangle is 180 degrees but if you see sum of three 90 degrees is 270 degrees.You can just see why there can't be more than 1 right angle in a triangle

Answer 6

A rhombus can not have all 4 acute angles

a rhombus has 4 equal sides, so you could call a square a special kind of rhombus, but you still do not have 4 acute angles.

Also, depending on your definition, ii may not exist.
