Worksheet 10 of 10 (100% complete)

Question 1

Question: Is triangle ABC a right triangle? Statement (1): Sides are 3, 4, and 5 units. Statement (2): Angles are in the ratio 1:2:3.

Statement (1): 3² + 4² = 9 + 16 = 25 = 5², satisfies Pythagoras → right triangle. Statement (2): Angles sum to 180°, ratio 1:2:3 gives angles 30°, 60°, 90° → right triangle.

Question 2

Question: What is the perimeter of triangle ABC? Statement (1): AB = 5 cm, BC = 7 cm Statement (2): Triangle is isosceles with AC as base

Even together, we don't know if AB = AC or BC = AC. Multiple possibilities exist.

Question 3

Question: What is the perimeter of triangle ABC? Statement (1): AB = 5 cm, BC = 7 cm Statement (2): Triangle is isosceles with AC as base

Even together, we don't know if AB = AC or BC = AC. Multiple possibilities exist.

Question 4

Question: What is the area of triangle ABC? Statement (1): Base BC = 8 cm Statement (2): Height from A to BC = 5 cm

Area = (1/2) × base × height = (1/2) × 8 × 5 = 20 cm².

Question 5

Question: Is triangle ABC a right triangle? Statement (1): Sides are 3, 4, and 5 units. Statement (2): Angles are in the ratio 1:2:3.

Statement (1): 3² + 4² = 9 + 16 = 25 = 5², satisfies Pythagoras → right triangle. Statement (2): Angles sum to 180°, ratio 1:2:3 gives angles 30°, 60°, 90° → right triangle.

Question 6

Question: What is the perimeter of triangle ABC? Statement (1): AB = 5 cm, BC = 7 cm Statement (2): Triangle is isosceles with AC as base

Even together, we don't know if AB = AC or BC = AC. Multiple possibilities exist.

Question 7

Question: What is the area of triangle ABC? Statement (1): Base BC = 8 cm Statement (2): Height from A to BC = 5 cm

Area = (1/2) × base × height = (1/2) × 8 × 5 = 20 cm².

Question 8

Question: What is the perimeter of triangle ABC? Statement (1): AB = 5 cm, BC = 7 cm Statement (2): Triangle is isosceles with AC as base
