What are the angle of an isosceles right angle triangle?
Isosceles Right Triangle has one of the angles exactly 90 degrees and two sides which is equal to each other. Since the two sides are equal which makes the corresponding angle congruent.
What is a triangle called if all the angles and all the sides are equal?
equilateral triangle
An equilateral triangle has three equal sides and angles. It will always have angles of 60° in each corner.
What are the sides and angles of a triangle?
A triangle has three sides, three angles, and three vertices. The sum of all internal angles of a triangle is always equal to 180°. This is called the angle sum property of a triangle. The sum of the length of any two sides of a triangle is greater than the length of the third side.
What are the sides of an isosceles triangle?
In an isosceles triangle that has exactly two equal sides, the equal sides are called legs and the third side is called the base. The angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles. The vertex opposite the base is called the apex.
Is an isosceles triangle a right triangle?
An Isosceles Right Triangle is a right triangle that consists of two equal length legs. Since the two legs of the right triangle are equal in length, the corresponding angles would also be congruent.
What are the sides of a triangle?
Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs. All triangles are convex and bicentric.
What do all 3 sides of a triangle equal?
An equilateral triangle has all three sides equal, and all three interior angles equal, too. In this case, each interior angle of an equilateral triangle is 60 degrees. An equilateral triangle is sometimes referred to as an equiangular triangle because all three angles are equal.
How many sides are there in a triangle?
3
Triangle/Number of edges
Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs. All triangles are convex and bicentric.
What are the angles of a triangle with 2 equal sides?
Terminology. In an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base. The angle opposite the base is called the vertex angle, and the point associated with that angle is called the apex. The two equal angles are called the isosceles angles.
