An acute angle is less than 90 degrees, a right angle is exactly 90 degrees, no more or no less, and an obtuse angle is more than 90 degrees but less than 180 degrees. Does that answer your question?

Every triangle have 6 main parts: 3 sides and 3 angles. On a right triangle one of the angles has to be a right angle, meaning it has a 90 degree angle.

A quadrilateral is a 4 sided shape whose 4 interior angles add up to 360 degrees.

Parallelograms: 1.)opposite side of a parallelogram are parallel and you can prove that by finding the slope for both lines. 2.) opposite sides of a parallelogram are congruent 3.) diagonals bisect each other 4.)opposite angles are congruent 5.) consecutive angles are supp. *Remember that alternate interior angles are congruent.

All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are graded as follows:- Scalene triangle has 3 different acute angle Right angle triangle has a 90 degree angle and 2 acute angles Obtuse triangle has 1 obtuse angle and 2 acute angles Equilateral triangle has 3 equal sides and 3 equal angles of 60 degrees Isosceles triangle has 2 equal sides and 2 equal base angles

There are right angles, acute angles, obtuse angles, and straight angles.
