How are the angles of an equilateral triangle related quizlet?

If two sides of a triangle are congruent, then the angles opposite those sides are congruent. If two angles of a triangle are congruent, then the sides opposite those angles are congruent. A triangle is equilateral if and only if it is equiangular. Each angle of an equilateral triangle measures 60 degrees.

How are the angles in a triangle related?

The three interior angles in a triangle will always add up to 180°. At each corner the exterior and interior angles are on a straight line, so at each corner these two angles add up to 180°. An isosceles triangle has two lengths which are the same as each other, and two angles which are the same as each other.

Does equilateral triangle have same angles?

Equilateral. An equilateral triangle has three equal sides and angles. It will always have angles of 60° in each corner.

Which word describes each angle in an equilateral triangle?

Equilateral Triangle: Three equal sides. Three equal angles, always 60°. An equilateral triangle is a triangle having all three sides of equal length. Acute Triangle:All angles are less than 90°.

Are all equilateral triangles isosceles explain quizlet?

always (An equilateral triangle has 3 congruent sides An isosceles triangle must have at least 2 congruent sides. Since an equilateral triangle has at least 2 congruent sides all equilateral triangles must be isosceles.

Why are the angles in an equilateral triangle equal?

Explanation: An equilateral triangle is one in which all three sides are congruent. It also has the property that all three interior angles are equal. Since all sides are congruent, the other two sides both measure 12 centimeters.

Which statement best describes an equilateral triangle?

In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

Are equilateral triangles also isosceles?

An isosceles triangle therefore has both two equal sides and two equal angles. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal. Another special case of an isosceles triangle is the isosceles right triangle.

Are equilateral triangles scalene?

Scalene triangles have no equal sides and no equal angles. Equilateral triangles have three equal sides and three equal angles.
