Two angles that add up to 90 degrees?
complementary angles..there are a lot any 2 angles when added together that make 90 degreesComplementary
What is the supplement of a acute angle?
First, an acute angle is an Angle that is less than a right angle (<90°) Secondly, an obtuse angle is one that is more than a right angle but less then a straight angle (<180°) then, the complementary angles of a pair of angles is 90° or a Right angle and the complement of an acute angle is the amount needed of an unknown angle (against known angles) to make 90° or a right angle a supplementary angle are a pair of angles which, when Added together, make 180° or a straight line. and the suplement to an angle is the value of an unknow angle to to be added on to make 180°
Can you draw a rhombus with congruent sides and angles?
Sure ! -- The sides of every rhombus are always congruent. -- If you make the angles congruent, then you have a special kind of rhombus called a "square".
Two angels added together to equal 180 degrees are?
Two angels that are add together to make 180 are 90 and 90
Why the triangle is 180 and the rectangle is 360?
There is a theorem which proves that the interior angles of a triangle add to 180o. It is too difficult to show the proof here, but you can easily make a demonstration: cut a triangle out of paper; make a pencil mark in each corner of the triangle. Cut or tear off each corner, and fit thethreemarked angles together. They should make a straight edge, which is a 180o angle.Draw a line joining two opposite corners of a rectangle; you have divided it into two triangles. Each of these triangles has angles that add to 180o; together, the six angles of the twotrianglesform the angles of therectangle and must add to 2x180o = 360o.
