Have two equal sides and two equal angles.It has one obtuse angle and two acute angles which are equal in measure and each less than 45 degrees.The properties of an isosceles obtuse triangle are listed below: What are the Properties of an Isosceles Obtuse Triangle? The base is the side opposite to the vertex from where the height is drawn or measured. The area of an obtuse isosceles triangle can be calculated by using the formula: Area = 1/2 × base × height square units. How to Find the Area of an Isosceles Obtuse Triangle? Some examples of isosceles obtuse triangle angles are given below: We just need one obtuse angle and two acute angles each less than 45° and equal in measurement. Yes, it is possible to draw an isosceles obtuse triangle. Is an Obtuse Isosceles Triangle Possible? One example of the obtuse isosceles triangle angles is 40°, 40°, and 100°. In this triangle, there is one obtuse angle and the other two angles are equal in measurement and are acute angles. So, the perimeter of an isosceles obtuse triangle = (2a + b) units, where a is the length of the equal side and b is the length of the unequal side of the triangle.įAQs on Isosceles Obtuse Triangle What is an Isosceles Obtuse Triangle?Īn isosceles obtuse triangle is a triangle that comes in the category of both obtuse triangles and isosceles triangles. To find the isosceles obtuse triangle perimeter, we just have to add the length of all three sides. Look at the image given below showing isosceles obtuse triangle formulas for finding area and perimeter. Where a and b are the sides of the triangle and s is the semi-perimeter, which is (a + a + b)/2 or (2a+b)/2. If the length of all three sides are given, then area = \((s-a) \sqrt\).If the length of base and height of the triangle is given, then area = square units. There are two possible formulae that can be used to find the area of an isosceles obtuse triangle based on what information is given to us. The formula of an isosceles obtuse triangle is useful to find the area and perimeter of the triangle.
