what is a 3 sided polygon with 1 right angle?
A 3-sided polygon with 1 right angle is called a right triangle. To understand and find a right triangle, you need knowledge of basic geometry concepts and properties of triangles.
A right triangle is a triangle that has one angle measuring exactly 90 degrees (a right angle). In addition to the right angle, a right triangle has two other angles, and the sum of all three angles in any triangle is always 180 degrees.
To identify or construct a right triangle, you can follow these steps:
1. Start with any triangle.
2. Measure the angles of the triangle using a protractor or knowledge of angle classifications. Ensure that one of the angles measures exactly 90 degrees (a right angle).
3. Check if the other two angles sum up to 90 degrees. If they do, then your triangle is a right triangle.
Alternatively, you can also identify or construct a right triangle using the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. So, if you know the lengths of the sides of a triangle, you can check if it is a right triangle by verifying if the Pythagorean theorem holds true.
Remember, a triangle can only have one right angle, so if you find a triangle with more than 1 right angle, it is not a valid triangle.
