A right angle triangle is a triangle with one angle that measures exactly 90 degrees. This angle is called the right angle and is denoted by a small square in the corner of the triangle.
A right angle triangle has three sides and three angles. The side opposite the right angle is called the hypotenuse and is the longest side. The other two sides are called the legs. The Pythagorean theorem, a² + b² = c², is a key property of right angle triangles.
To find the missing side of a right angle triangle, you can use the Pythagorean theorem, a² + b² = c². If you know the lengths of two sides, you can solve for the third side using this equation. Alternatively, you can use trigonometric ratios such as sine, cosine, or tangent to find the missing side.
Right angle triangles are used in many real-life situations, such as construction, architecture, and engineering. They are also used in navigation and surveying to calculate distances and angles. Additionally, right angle triangles are important in physics and astronomy for calculating forces and distances between objects.
To draw a right angle triangle, you will need a straight edge and a protractor. First, draw a straight line for the hypotenuse. Then, using the protractor, measure and mark a 90-degree angle at one end of the line. Finally, draw the remaining two sides to complete the triangle.
