## 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…

## How do you find the area of two triangles together?

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

## What does all triangles have in common?

All of these triangles have four things in common, and those are bases, altitudes, heights, and areas, and they are related in the formula for the area of a triangle.

## What is a equilateral triangle look like?

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°.

## How many sides are there in a triangle?

## How do you know if a triangle is acute?

Classifying Triangles You can determine whether a triangle is acute, right, or obtuse by its side lengths. In TABC with longest side c: If c2 a2 b2, then TABC is acute. If c2 a2 b2, then TABC is right.

## What is a true triangle?

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted .

## What is the name of Triangle?

Name of TriangleDescriptionEquilateral TriangleA triangle whose three sides have the same length. These sides of equal length are called congruent sides.Isosceles TriangleA triangle with exactly two congruent sides.Scalene TriangleA triangle in which all three sides are a different length.

## Can a triangle have 3 right angles?

No, real, triangle can have three right angles. The sum of the angles formed must equal 180° and the sum of the length of two sides must be greater than the length of the third.
