# 45 45 90 Worksheet: Understanding the Basics of This Special Right Triangle

The 45 45 90 triangle is a special type of right triangle. It has three sides, two of which are equal in length. Such a triangle has several unique properties that make it useful for mathematical calculations. Understanding the basics of the 45 45 90 worksheet can be a great help to students who are learning geometry and trigonometry.

The main feature of the 45 45 90 triangle is its angles. The two equal sides create two angles that measure 45 degrees each. The other side forms a right angle, or 90 degrees. Knowing these angles helps mathematicians solve for unknown lengths and angles when the other side lengths are known. Using a 45 45 90 worksheet can help students practice solving for those unknowns.

The ratio of the lengths of the sides of a 45 45 90 triangle is also important. The two equal sides form a proportion of 1:1. The remaining side is always double the length of the other two sides. This ratio helps in solving certain problems involving the triangle.

The 45 45 90 worksheet can also help students practice solving for area, perimeter, and circumference of such triangles. Knowing the sides of the triangle and the angles makes it relatively easy to calculate area and perimeter. The circumference, however, can be more difficult to calculate as it requires knowledge of the Pythagorean theorem. The 45 45 90 worksheet can provide students with practice problems for each concept.

The 45 45 90 worksheet can also teach students about the properties of the triangle and help them understand its unique features. It can also be used to reinforce their knowledge of the Pythagorean theorem and other related concepts. By working through problems on the worksheet, students can gain a better understanding of how to use the triangle in various mathematical problems.
