Identify the triangle PQR as isosceles ( two sides equal length) equilateral (three sides of equal length) a right triangle, or a scalene triangle (three sides of different length)
What triangle?
To identify the triangle PQR as isosceles, equilateral, a right triangle, or a scalene triangle, we need to know the lengths of its sides. Here's how you can determine the type of triangle PQR:
Step 1: Measure the lengths of the sides
Using a ruler or any measuring tool, measure the lengths of sides PQ, QR, and RP. Write down or remember these measurements.
Step 2: Compare the side lengths
- If all three sides (PQ, QR, RP) are of equal length, then PQR is an equilateral triangle.
- If only two sides of the triangle are of equal length, then PQR is an isosceles triangle.
- If all three sides have different lengths, then PQR is a scalene triangle.
Step 3: Check for a right angle (optional)
If you suspect that PQR might be a right triangle (one angle measures 90 degrees), you can measure the angles using a protractor. If one of the angles is a right angle, then PQR is a right triangle. However, this step is not necessary to determine if PQR is isosceles, equilateral, or scalene.
By following these steps, you will be able to identify the type of triangle PQR based on its side lengths.
