## What is the longest side of a right triangle called?

hypotenuseThe hypotenuse of a right triangle is always the side opposite the right angle.

It is the longest side in a right triangle.

The other two sides are called the opposite and adjacent sides..

## What are the 4 different types of triangles?

This math worksheet gives your child practice identifying equilateral, isosceles, scalene, and right triangles.

## What are two ways to classify triangles?

Triangles are classified, or grouped, in two different ways. One classification distinguishes among the sides, and another by the angles. For a triangle, you can have all three sides congruent (equal measure), or two sides congruent, or no sides congruent.

## What does a obtuse triangle look like?

An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°. Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees.

## What angles do triangles have?

A triangle has three angles. The sum of the measures of the angles is always 180° in a triangle. We have different types of triangles. A triangle is classified by its angles and by the number of congruent sides.

## Do equilateral triangles have equal angles?

Yes, because a equilateral triangle has 3 equal angles. The 3 angles of a triangle equal 180°. So if the angles are all equal in an equilateral triangle, we do 60 times 3 which equals 180°.

## How do you classify a triangle?

When classifying a triangle by its sides, you should look to see if any of the sides are the same length. If no sides are the same length, then it is a scalene triangle. If two sides are the same length, then it is an isosceles triangle. If all three sides are the same length, then it is an equilateral triangle.

## What is called triangle?

A triangle is a 3-sided polygon sometimes (but not very commonly) called the trigon. … 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.

## What are the three types of triangle?

What are the types of triangle?The sum of angles in any triangle is 180°. … An equilateral triangle has three equal sides and angles. … An isosceles triangle can be drawn in many different ways. … A right-angled triangle has one 90° angle. … A scalene triangle has three different angles and none of its sides are equal in length.More items…

## What are the 7 types of triangles?

To learn about and construct the seven types of triangles that exist in the world: equilateral, right isosceles, obtuse isosceles, acute isosceles, right scalene, obtuse scalene, and acute scalene.

## What 3 angles make a triangle?

In a Euclidean space, the sum of angles of a triangle equals the straight angle (180 degrees, π radians, two right angles, or a half-turn). A triangle has three angles, one at each vertex, bounded by a pair of adjacent sides.

## How do you classify a triangle by its side lengths?

Equilateral triangle: A triangle with three sides of equal length. Isosceles triangle: A triangle with at least two sides of equal length. Line of symmetry: A line through a figure that creates two halves that match exactly. Obtuse angle: An angle with a measure greater than 90 degrees but less than 180 degrees.

## What is a true triangle?

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.

## What are 3 ways to classify a triangle by its sides?

Classifying Triangles by Sidesscalene triangle-a triangle with no congruent sides.isosceles triangle-a triangle with at least 2 congruent sides (i.e. 2 or 3 congruent sides)equilateral triangle-a triangle with exactly 3 congruent sides.NOTE: Congruent sides means that the sides have the same length or measure.

## Is an acute triangle?

An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). … Since a triangle’s angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.

## Can triangles have curved sides?

There are two ways I triangle can have curved sides—in one case the sides curve in, and in the other the sides curve out. In the first case, the triangle is called “hyperbolic”—see Hyperbolic triangle —and in the the second, the triangle is called “spherical”—see Spherical geometry .

## How many sides are there in a triangle?
