Angle rules with parallel lines — Homework
Use the parallel-line angle rules or the triangle angle-sum rule to find each missing angle.
- 1.One angle at a transversal-parallel crossing is 55 degrees. Find its corresponding angle.
- 2.Using the 55-degree angle above, find its co-interior angle.
- 3.A triangle has angles 40 degrees and 90 degrees. Find the third angle.
- 4.One angle formed by a transversal is 110 degrees. Find its alternate exterior angle and explain the rule you used.
- 5.A triangle has one angle of 90 degrees and another of 35 degrees. Find the third angle, then explain what type of triangle this is by its angles.
