In a right-angled triangle, what is the name of the side opposite the right angle?

• Leg

• Altitude

• Hypotenuse

• Median

What is the relationship between the lengths of the legs (a, b) and the hypotenuse (c) in a right-angled triangle?

• a + b = c

• a² + b² = c²

• a² - b² = c²

• a + b = c²

Which of the following statements is true about the diagonals of a rhombus?

• They are always equal in length.

• They bisect each other at right angles.

• They are parallel to each other.

• They only bisect the angles of the rhombus.

What is the relationship between the side (a) of a rhombus and its diagonals (d1 and d2)?

• a² = d1² + d2²

• a = d1 + d2

• a² = (d1² + d2²) / 4
