What is a triangle with 3 equal sides?
Equilateral
Equilateral. An equilateral triangle has three equal sides and angles. It will always have angles of 60° in each corner.
How many sides are equal in isosceles triangle?
two sides
In geometry, an isosceles triangle is a triangle that has two sides of equal length.
Does a triangle have 3 equal angles?
An equilateral triangle has three equal length sides and three equal inside angles.
Which two angles are equal in an isosceles triangle?
Properties of Isosceles Triangle The two equal sides of an isosceles triangle are called the legs and the angle between them is called the vertex angle or apex angle. The side opposite the vertex angle is called the base and base angles are equal.
What is the third side of an isosceles triangle called?
For an isosceles triangle with only two congruent sides, the congruent sides are called legs. The third side is called the base. The angle opposite the base is called the vertex angle, and the angles opposite the legs are called base angles.
Do all equilateral triangles have the properties of an isosceles triangle?
An isosceles triangle two angles will also be the same in front of the equal sides. If all three sides are equal in length then it is known as an equilateral triangle. Therefore we may conclude that all equilateral triangles also have all the properties of an isosceles triangle.
What is the difference between isosceles triangle and apex angle?
The two angles opposite to the equal sides are congruent to each other. That means it has two congruent base angles and this is called an isosceles triangle base angle theorem. The angle which is not congruent to the two congruent base angles is called an apex angle.
What is an isosceles triangle base angle theorem?
That means it has two congruent base angles and this is called an isosceles triangle base angle theorem. The angle which is not congruent to the two congruent base angles is called an apex angle.
