Obtuse Isosceles Triangle
Below is a picture of an obtuse Isosceles triangle. But, let us first define what an Obtuse Isosceles triangle is.
What is an Obtuse Isosceles Triangle?
The definition of an Obtuse Isosceles triangle is that same as an Isosceles triangle but where the two equal sides meet is not an acute angle, as in the case of Acute Isosceles triangles, but an Obtuse angle. This gives rise to the name Obtuse Isosceles triangle.
In this Obtuse Isosceles triangle picture, the two parallel sides are shown as well as the obtuse angle marked by the red circle. This obtuse angle is clearly greater than 90 degrees making this triangle an Obtuse Isosceles triangle. Below are more pictures of Obtuse Isosceles triangles.
