A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. The side opposite the obtuse angle in the triangle is the longest. Obtuse angled triangles in real life: In

An obtuse-angled triangle can be scalene or isosceles, but never equilateral. Explanation: . Since the triangle is isosceles, we know that 2 of the angles (that sum up to 180) must be equal. The question states that the noncongruent angles average 55°, thus providing us with a system of two equations: Now, based on the properties of an isosceles triangle, you can draw the following as well: Based on your standard reference triangle, you know: Therefore, is . This means that is and the total base of the triangle is . Now, the area of the triangle is: or In an isosceles triangle, at least two angles measure the same.

Draw and label each of the other types of triangles in the drawing. THIS SET IS OFTEN IN FOLDERS WITH Isosceles Obtuse Triangle.

Whether an isosceles triangle is acute, right or obtuse depends only on the angle at its apex. In Euclidean geometry, the base angles can not be obtuse (greater than 90°) or right (equal to 90°) because their measures would sum to at least 180°, the total of all angles in any Euclidean triangle.

An obtuse triangle is any triangle that has an obtuse angle. An obtuse angle is one that measures greater than 90 degrees. An acute angle is one that measures less than 90 degrees. A scalene An obtuse triangle is a triangle that has one obtuse angle, meaning an angle that is greater than 90 degrees but less than 180 degrees. So, for an isosceles triangle to be considered obtuse, it just has to be a triangle with two equal sides and an angle that is in between 90 degrees and 180 degrees.

So the equation to solve becomes . Thus, 65 is the base angle and 50 is the vertex angle.
