What is a triangle with 3 congruent sides?

What is a triangle with 3 congruent sides?

Equilateral triangle: three congruent sides and three congruent angles (three sides of equal length and three angles of equal measure).

What triangle is formed by joining three line segments?

A triangle is a figure formed by three segments joining three noncollinear points. Each of the three points joining the sides of a triangle is a vertex. The plural of vertex is “vertices.” In a triangle, two sides sharing a common vertex are adjacent sides.

Which triangle fits the following description a triangle with 3 congruent sides and 3 acute angles?

equilateral triangleA triangle with three congruent sides. Acute TriangleAn acute triangle has three angles that each measure less than 90 degrees. Interior anglesInterior angles are the angles inside a figure.

How do you find a scalene triangle?

We can find the scalene triangle’s area when the length of its two sides and the included angle are given.

1. When two sides b and c and included angle A is known, the area of the triangle is, Area = (1/2) bc × sin A.
2. When sides a and c and included angle B is known, the area of the triangle is, Area = (1/2) ac × sin B.

What is the perimeter of a triangle with vertices?

Perimeter= 3 + 5 + 4 = 12 To find the perimeter of the triangle, find the lengths of each side of the triangle using the distance formula. Use the distance formula to find the length between point A and B, B and C, C and A. Then add all three lengths together to get the perimeter.

How do we find the perimeter of a triangle?

To calculate the perimeter of a triangle, add the length of its sides. For example, if a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c.

How do you find the perimeter of a triangle without knowing the sides?

There are three primary methods used to find the perimeter of a right triangle.

1. When side lengths are given, add them together.
2. Solve for a missing side using the Pythagorean theorem.
3. If we know side-angle-side information, solve for the missing side using the Law of Cosines.

What is a perimeter formula?

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The perimeter, P, is: P=x+x+y+y.

What has the same perimeter as a triangle?

An equilateral triangle has the same perimeter as a square.
