To determine which of the triangles are right triangles among options 1, 2, 3, and 4, we need to check the angles of each triangle. A right triangle is defined as having one angle equal to 90 degrees.
Here’s how to identify each triangle:
- Triangle 1: Measure the angles. If one angle is 90 degrees, then this is a right triangle.
- Triangle 2: Again, check if any angle measures 90 degrees.
- Triangle 3: Similar checks apply. Look for a 90-degree angle.
- Triangle 4: Lastly, verify the angles in triangle 4.
After checking all four triangles, you’ll be able to identify which one or more are right triangles based on the presence of a 90-degree angle in their measurements.
