U4HW1: Classifying Triangles

Front

What is a triangle?

Back

A triangle is a polygon with three edges and three vertices.

Front

What are the types of triangles based on sides?

Back

1. Equilateral: All sides are equal. 2. Isosceles: Two sides are equal. 3. Scalene: All sides are different.

Front

How do you classify a triangle with two equal sides?

Back

It is classified as an Isosceles triangle.

Front

What is an equilateral triangle?

Back

An equilateral triangle is a triangle in which all three sides are of equal length.

Front

What is a scalene triangle?

Back

A scalene triangle is a triangle in which all three sides have different lengths.

Front

If a triangle has sides of lengths 5, 5, and 8, how is it classified?

Back

It is classified as an Isosceles triangle.

Front

If a triangle has sides of lengths 3, 4, and 5, how is it classified?

Back

It is classified as a Scalene triangle.

Front

What is the formula to find the length of a side of a triangle using coordinates?

Back

The distance formula: d = √((x2 - x1)² + (y2 - y1)²) is used to find the length of a side between two points (x1, y1) and (x2, y2).

Front

What is the significance of classifying triangles?

Back

Classifying triangles helps in understanding their properties and relationships, which is essential in geometry.

Front

What is the distance between points J(-2,3) and K(5,5)?

Back

The distance is √((5 - (-2))² + (5 - 3)²) = √(7² + 2²) = √(49 + 4) = √53.
