Triangle 1 is a triangle with two congruent sides, AC and AB. Use the slider to adjust the length of the legs. How do the base angles change? What is the relationship between the base angles? When the legs are long, what can you say about the measure of the base angles? You can also drag the points to manipulate Triangle 1.
Triangle 2 is a triangle with two congruent base angles. Use the slider to adjust the measure of the base angles. How do the legs change? What is the relationship between the legs? When the measure of the base angles is small, what can you say about the length of the legs?You can also drag the points to manipulate Triangle 2.
