Congruent and Similar Triangle Investigation Activity One You and your partner need to get onto the computer and go to . Both of you will decide on the side lengths of a triangle. Using the segment with given length tool button, found in the drop down menu of the button tool third from the left, create said triangle. You can move your segments by clicking the blue point, and rotating by clicking the gray point on your segments. There are multiple places to put your side length measurements so that you can try this activity with multiple side lengths. Side lengths: AB=____________ BC=_______________ CA=__________________ Side lengths: AB=____________ BC=_______________ CA=__________________ Side lengths: AB=____________ BC=_______________ CA=__________________ Measure each angle with the angle tool (picture of an angle 5th from the right), it’s the angle tool on the same menu as the Distance or Length tool. Angles: ∠ A=____________ B∠ = ____________ ∠C =¬¬¬¬___________ Angles: ∠ A=____________ B∠ = ____________ ∠C =¬¬¬¬___________ Angles: ∠ A=____________ B∠ = ____________ ∠C =¬¬¬¬___________ Compare your triangle to your partners What do you notice? Is your triangle congruent to your partners triangle? Justify your answer. What was the minimum amount of information used to create these two congruent triangles? Can you replicate this process in the same manner?
