What is a triangle with all sides called?

What is a triangle with all sides called?

A triangle with all sides equal is called equilateral, a triangle with two sides equal is called isosceles, and a triangle with all sides a different length is called scalene. A triangle can be simultaneously right and isosceles, in which case it is known as an isosceles right triangle.

What is an interior angle of a triangle called?

The angles inside a triangle are called interior angles. 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°.

What is a triangle called when all sides and angles are congruent?

Equiangular Triangle: A triangle where all the angles are congruent. You can also classify a triangle by its sides. Scalene Triangle: A triangle where all three sides are different lengths.

What is the name of all triangles?

The six types of triangles are: isosceles, equilateral, scalene, obtuse, acute, and right.

• An isosceles triangle is a triangle with two congruent sides and one unique side and angle.
• An equilateral triangle is a triangle with three congruent sides and three congruent angles.

What is a interior triangle?

The interior of the triangle is the set of all points inside a triangle, i.e., the set of all points in the convex hull of the triangle’s vertices. If the hull has three points, the point lies in the triangle’s interior; if it is four, it lies outside the triangle. …

What is an internal triangle?

A triangle is formed by connecting the endpoints of three line segments as a closed geometric shape. The intersection of every two sides of a triangle forms an angle internally. Hence, the angle is called an interior angle of triangle. It is also called as an internal angle of a triangle.

What is the name of all the triangles?

What are the names of the sides of a right triangle?

In a right triangle, the hypotenuse is the longest side, an “opposite” side is the one across from a given angle, and an “adjacent” side is next to a given angle.

What are the sides of a right triangle called?

The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees… The two sides of the triangle that are by the right angle are called the legs… and the side opposite of the right angle is called the hypotenuse.

What are the names of the legs of a triangle?

! Legs, base, vertex angle, and base angles. In an isosceles triangle, the two equal sides are called legs, and the third side is called the base. The angle formed by the two equal sides is called the vertex angle. The other two angles are called base angles (Figure 1 ).

What are the names of the sides of an isosceles triangle?

In an isosceles triangle, the two equal sides are called legs, and the third side is called the base. The angle formed by the two equal sides is called the vertex angle. The other two angles are called base angles (Figure 1).

What are the interior angles of a triangle?

A triangle’s interior angles are ∠ HOP, ∠ HPO and ∠ PHO. ∠ HOP is 64° and m ∠ HPO is 26°. What is m ∠ PHO? To explore the truth of the statements you can use Math Warehouse’s interactive triangle , which allows you to drag around the different sides of a triangle and explore the relationships betwen the measures of angles and sides.
