In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. This statement is known as the:

  1. Pythagorean Theorem

  2. Euclidean Theorem

  3. Converse of Pythagorean Theorem

  4. Leg Theorem


Correct Option: A
Explanation:

The Pythagorean Theorem is a fundamental theorem in geometry that states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

If the legs of a right triangle are 3 cm and 4 cm, what is the length of the hypotenuse?

  1. 5 cm

  2. 7 cm

  3. 12 cm

  4. 16 cm


Correct Option: A
Explanation:

Using the Pythagorean Theorem, we have: (a^2 + b^2 = c^2). Substituting the values, we get: (3^2 + 4^2 = c^2). Simplifying, we get: (9 + 16 = c^2). Therefore, (c^2 = 25) and (c = 5).

In a right triangle, if the hypotenuse is 10 cm and one leg is 6 cm, what is the length of the other leg?

  1. 4 cm

  2. 8 cm

  3. 12 cm

  4. 16 cm


Correct Option: B
Explanation:

Using the Pythagorean Theorem, we have: (a^2 + b^2 = c^2). Substituting the values, we get: (6^2 + b^2 = 10^2). Simplifying, we get: (36 + b^2 = 100). Therefore, (b^2 = 64) and (b = 8).

The Pythagorean Theorem can be used to find the distance between two points in a coordinate plane. True or False?

  1. True

  2. False


Correct Option: A
Explanation:

The Pythagorean Theorem can be used to find the distance between two points in a coordinate plane. The distance between two points ((x_1, y_1)) and ((x_2, y_2)) is given by the formula: (d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}). This formula is derived using the Pythagorean Theorem.

In a right triangle, the ratio of the square of the hypotenuse to the square of one leg is equal to the ratio of the square of the other leg to the square of the hypotenuse. This statement is known as the:

  1. Converse of Pythagorean Theorem

  2. Leg Theorem

  3. Pythagorean Triple

  4. Pythagorean Identity


Correct Option: A
Explanation:

The Converse of Pythagorean Theorem states that if the square of one side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.

A Pythagorean triple is a set of three positive integers that satisfy the Pythagorean Theorem. Which of the following is a Pythagorean triple?

  1. (3, 4, 5)

  2. (5, 12, 13)

  3. (8, 15, 17)

  4. (10, 24, 26)


Correct Option: A
Explanation:

A Pythagorean triple is a set of three positive integers that satisfy the Pythagorean Theorem. The most common Pythagorean triple is (3, 4, 5). Other Pythagorean triples include (5, 12, 13), (8, 15, 17), and (10, 24, 26).

The Pythagorean Theorem can be used to find the area of a right triangle. True or False?

  1. True

  2. False


Correct Option: A
Explanation:

The Pythagorean Theorem can be used to find the area of a right triangle. The area of a right triangle is given by the formula: (A = \frac{1}{2}ab), where (a) and (b) are the lengths of the two legs of the triangle. This formula is derived using the Pythagorean Theorem.

In a right triangle, the square of the hypotenuse is equal to the difference of the squares of the other two sides. True or False?

  1. True

  2. False


Correct Option: B
Explanation:

In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides, not the difference.
