What are the three names of the sides of a 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. We use special words to describe the sides of right triangles.
What are the names of each side of a triangle?
Sides Of A Right Triangle
- the side PQ, which is opposite to the right angle PRQ is called the hypotenuse. The hypotenuse is the longest side of the right triangle.
- the side RQ is called the adjacent side of angle θ.
- the side PR is called the opposite side of angle θ.
What are the parts of a triangle in geometry?
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.
Which triangle has two sides?
isosceles triangle
An isosceles triangle therefore has both two equal sides and two equal angles. The name derives from the Greek iso (same) and skelos (leg). A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle.
How many sides does triangle have?
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.
How many corners are there in triangle?
| Triangle | |
|---|---|
| Edges and vertices | 3 |
| Schläfli symbol | {3} (for equilateral) |
| Area | various methods; see below |
| Internal angle (degrees) | 60° (for equilateral) |
What are the sides of a triangle called?
The two equal sides are called the legs and the third side is called the base of the triangle. The other dimensions of the triangle, such as its height, area, and perimeter, can be calculated by simple formulas from the lengths of the legs and base.
What are the names of the three sides of a right triangle?

What are the rules for the sides of a triangle?
Triangle Inequality Theorem One. According to the first triangle inequality theorem,the lengths of any two sides of a triangle must add up to more than the length of the
What are the three sides of a triangle?
There are three types of triangles: equilateral, isosceles and scalene. The equilateral triangle has three sides that are all equal in length. The angles formed where sides of the triangle meet are all equal to 60 degrees. The isosceles triangle has two congruent sides, and two of its angles are also equal.
