Task 1: Proving Triangle Similarity

To prove the similarity between triangles ABC and NMR, we need to show that their corresponding angles are equal and their corresponding sides are proportional.

Given: - Angle A = Angle N = 72 degrees - AB = 12, AC = 9 - NM = 8, NP = 6

To prove the similarity, we will compare the corresponding angles and sides.

1. Comparing Angles: - Angle A = Angle N (Given: 72 degrees) - Angle B = Angle M (Corresponding angles of similar triangles) - Angle C = Angle R (Corresponding angles of similar triangles)

Therefore, the corresponding angles of triangles ABC and NMR are equal.

2. Comparing Sides: - AB = 12, NM = 8 - AC = 9, NP = 6

To check if the sides are proportional, we can calculate the ratios of the corresponding sides:

- AB/NM = 12/8 = 1.5 - AC/NP = 9/6 = 1.5

The ratios of the corresponding sides are equal.

Therefore, we have shown that the corresponding angles of triangles ABC and NMR are equal, and the corresponding sides are proportional. Hence, triangles ABC and NMR are similar.

Task 2: Proving Triangle Similarity

To prove the similarity between triangles ABC and NMP, we need to show that their corresponding angles are equal and their corresponding sides are proportional.

Given: - AB = 12, BC = 16, AC = 24 - NM = 6, MP = 8, NP = 12

To prove the similarity, we will compare the corresponding angles and sides.

1. Comparing Angles: - Angle A = Angle N (Corresponding angles of similar triangles) - Angle B = Angle M (Corresponding angles of similar triangles) - Angle C = Angle P (Corresponding angles of similar triangles)

Therefore, the corresponding angles of triangles ABC and NMP are equal.

2. Comparing Sides: - AB = 12, NM = 6 - BC = 16, MP = 8 - AC = 24, NP = 12

To check if the sides are proportional, we can calculate the ratios of the corresponding sides:

- AB/NM = 12/6 = 2 - BC/MP = 16/8 = 2 - AC/NP = 24/12 = 2

The ratios of the corresponding sides are equal.

Therefore, we have shown that the corresponding angles of triangles ABC and NMP are equal, and the corresponding sides are proportional. Hence, triangles ABC and NMP are similar.

In conclusion, we have proven the similarity of triangles ABC and NMR in Task 1, and the similarity of triangles ABC and NMP in Task 2.
