• 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

• 5 cm

• 6 cm

• 7 cm

• 8 cm

In a right-angled triangle, if one acute angle is 30 degrees and the hypotenuse is 10 cm, what is the length of the leg opposite the 30-degree angle?

• 5 cm

• 5√3 cm

• 10 cm

What are the lengths of the two legs of a right-angled triangle if one acute angle is 30 degrees and the hypotenuse is 10 cm?

• 5 cm and 5√2 cm

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

• a = (d1 + d2) / 2
