WebIn an obtuse triangle, one of the angles of the triangle is greater than 90°, while in an acute triangle, all of the angles are less than 90°, as shown below. Triangle facts, theorems, and … Webof the Isosceles Triangle Theorem: (1) A triangle is equilateral if and only if it is equiangular. (2) Each angle of an equilateral triangle has a degree measure of 60. The congruent sides of the triangle imply that all the angles are congruent. We can also use the converse of this, which is that three congruent angles imply three

WebA straight angle is 180 degrees. The angles W and X form a straight line, added together together they measure 180 degrees. They are also know as Adjacent Angles. Adjacent Angles add up to 180 degrees. Adjacent Angles are also. ∠ Y and ∠ Z, ∠ W and ∠ Y. ∠ X and ∠ Z. The three angles of a triangle will always add up to 180 degrees. WebAll three angles in any triangle always add up to 180 degrees. So if you only have two of the angles with you, just add them together, and then subtract the sum from 180.
