# 7.3 Practice A Geometry Answers

Are you looking for answers to 7.3 Practice A Geometry questions? This article will provide you with the answers you need to help you understand the concepts better. Geometry is an important part of mathematics, so it is very important to understand it in order to do well in other math classes.

## Identifying a Triangle The first question in 7.3 Practice A Geometry is to identify a triangle. A triangle is a three-sided shape that has three angles and three sides. The angles of a triangle are always less than 180 degrees, and all of the sides must be the same length. A triangle can be either right, acute, or obtuse.

## Identifying the Sides of a Triangle The next question in 7.3 Practice A Geometry is to identify the sides of a triangle. The sides of a triangle are called the base, the legs, and the hypotenuse. The base is the longest side of a triangle, the legs are the two shorter sides of a triangle, and the hypotenuse is the longest side of a triangle. The hypotenuse is also the side opposite the right angle in a right triangle.

## Finding the Perimeter of a Triangle The next question in 7.3 Practice A Geometry is to find the perimeter of a triangle. The perimeter of a triangle is the sum of all of its sides. To find the perimeter of a triangle, simply add the lengths of all three sides together. For example, if a triangle has sides of 3, 4, and 5, then the perimeter would be 12 (3 + 4 + 5 = 12).

## Finding the Area of a Triangle The next question in 7.3 Practice A Geometry is to find the area of a triangle. The area of a triangle is equal to one-half of the base times the height. To find the area of a triangle, multiply the base times the height, then divide by two. For example, if a triangle has a base of 6 and a height of 8, then the area would be 24 (6 X 8 = 48; 48 / 2 = 24).

## Using the Pythagorean Theorem The last question in 7.3 Practice A Geometry is to use the Pythagorean Theorem. The Pythagorean Theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. To use the Pythagorean Theorem, first find the lengths of the two legs, then square them and add the squares together. Finally, find the square root of the sum to find the length of the hypotenuse.
