Question 6: Generalize what you know about the point of concurrency of the perpendicular bisectors of an acute triangle, a right triangle, and an obtuse triangle. Now we will explore a characteristic of the point of concurrency of the angle bisectors of a triangle. Let’s go back to our triangle in the calculator.

If a2 + b2 = c2, then it is a right triangle. If a2 + b2 < c2, then it is an acute triangle. If a2 + b2 > c2, then it is an obtuse triangle. Examples: What kind of triangle created by the side 6,8,and 10? In the right triangle, what is the missing side if the side is 5 and hypotenuse 25? Special Right Triangles. 30-60-90. Memorize:

An equilateral obtuse triangle is not possible because an equilateral triangle has equal angle measures (equiangular). A triangle can have no more than 180 however, by definition an obtuse angle is greater than. 90° . Multiplying a number greater than 90° by 3 will be greater than 180.
