Knots in doughnuts. We are given two solid doughnuts: one with a worm hole drilled as shown and the other with a knotted worm hole drilled as shown. Are these two-holed doughnuts equivalent?

2. The Polygon Exterior Angle Sum Theorem states the sum of the measures of the exterior angles of a polygon, one at each vertex, is 3. Two equations about interior angles in n-gons are given here. a. Explain what each one calculates. (n-2)180° STOP (n-2)180° n b. Apply both equations to a stop sign, like the one shown here. Use the equations and explain thoroughly.

What are the coordinates of all 4 verticies.

Gloria is recording her findings about the similar triangles shown, and she writes "AWVU-AYXZ" in her math journal. She then begins to look at corresponding sides and angles. How would you respond to Gloria? Choose the correct answer below. O A. It is true that the triangles are similar. However, Gloria should write "AWVU-AXYZ" instead. O B. Gloria cannot conclude that the triangles are similar since no information is given about the lengths of the sides. W OC. It is true that the triangles are similar. However, Gloria should write "AWVU = AYXZ" instead since that is more precise. V O D. It is true that the triangles are similar. However, Gloria should write "ΔυνW-ΔΧΥΖ" instead.
