What are the properties of obtuse triangle?
Obtuse Angled Triangle Properties The sum of the two angles other than the obtuse angle is less than 90 degrees. The side opposite to the obtuse angle is the longest side of the triangle. An obtuse triangle will have one and only one obtuse angle. The other two angles are acute angles.
How do you identify an acute triangle?
To determine whether the triangle is acute, right, or obtuse, add the squares of the two smaller sides, and compare the sum to the square of the largest side. Since this sum is greater, the triangle is acute.
What are the properties of different triangles?
Also, the angles opposite these equal sides are equal. Equilateral Triangle: All the sides are equal and all the three angles equal to 60°. Acute Angled Triangle: A triangle having all its angles less than 90°….Types of Triangle.

Does an acute triangle have equal sides?
Properties of Acute Triangles All equilateral triangles are acute triangles. An equilateral triangle has three sides of equal length and three equal angles of 60°. Acute triangles can be isosceles, equilateral, or scalene. The longest side of an acute triangle is opposite the largest angle.
What is acute angle?
Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.
How do you know whether a triangle is acute or obtuse?
An acute triangle has three angles that each measure less than 90 degrees. An obtuse triangle is a triangle with one angle that is greater than 90 degrees.
How many properties are there in triangle?
Five properties of a triangle are listed below: A triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side.
Are acute triangles scalene?
An acute triangle has all angles measuring less than 90º. Note: It is possible for an acute triangle to also be scalene, isosceles, or equilateral. A right triangle has one right angle.
