5. Why is it sufficient (enough) to know if just two pairs of angles are congruent in order to determine if triangles are similar? Why don't you need to know all three pairs?

Which graph represents the following piecewise defined function?

Find the solutions for a triangle with a =16, c =12, and b = 63º

Which of the following transformations will make coincide with ? a. counter-clockwise rotation 90º about a, followed by a translation 5 units to the right b. translation 5 units to the right, followed by a reflection across the y-axis c. translation 5 units to the right, followed by a reflection across the x-axis d. translation 1 unit up and 5 units to the right, followed by a reflection across the x-axis
