Given below is an example of an obtuse/oblique angle triangle. Obtuse/Oblique Angle Triangle | Properties of TriangleĪ triangle that has one angle that measures more than 90° is an obtuse angle triangle. Vice versa, we can say that if a triangle satisfies the Pythagoras condition, then it is a right-angled triangle. considering the above right-angled triangle ACB, we can say: In a right-angled triangle, the sum of squares of the perpendicular sides is equal to the square of the hypotenuse.įor e.g. The side opposite to the right angle is the largest side of the triangle and is called the hypotenuse.The other two angles of a right-angle triangle are acute angles.Right-Angle TriangleĪ triangle that has one angle that measures exactly 90° is a right-angle triangle. ![]() Given below is an example of an acute angle triangle. So, all the angles of an acute angle triangle are called acute angles.Let’s look into the six types of triangles in detail:Ī triangle that has all three angles less than 90° is an acute angle triangle.
