School has ended and the Riverdale High School cheerleading team, the River Vixens, are creating a new routine. They have been testing out several formations and have decided to create a triangle. Betty, Veronica, and Cheryl are at the vertices of the triangle. Betty is standing at (-7, 3), Veronica is standing at (9, 5), and Cheryl is in the front standing at (7, -5). The other River Vixens fill in the gaps between the vertices creating a triangle. 2. Determine the lengths of the three sides. Attach a picture of your work. * 1 Add file 1. Cheryl wants to make sure the routine is 3. State the type of triangle created. * perfect. She tells you to classify the triangle the River Vixens make in this formation. To Your answer do so you must draw the triangle on a set of Question 3 axis. A blank graph is provided for you if you (should you want to use it) or upload a picture of your work. * 1. The River Vixens decide it is time for a Question 2 new formation. Cheryl will stand at the origin, and the rest of the girls are to form a circle around her. Betty stands at (-8, 15).

Attach a picture of your work. 1 Add file 1. Cheryl isn't happy being in the front of the triangle. Instead, she wants to be at the exact center. She tells Melody to stand at (7, -5) and tells you to find the centroid algebraically of the triangle they've created. 2. Veronica stands at (11, -13). Is in the correct location? State whether she is inside, outside, or on the circle. Attach a picture of your work. Add this point to the graph from question 1. This will give her new location. Attach a 1 Add file nicture of
