Understanding Circle Geometry

What happens when a diameter is perpendicular to a chord in a circle?

• The chord is divided into two equal parts.

• The diameter becomes the radius.

• The circle's area is halved.

• The chord becomes the diameter.

If the diameter of a circle is 34 units, what is the length of the radius?

• 68 units

• 8.5 units

• 34 units

• 17 units

In a right triangle, if one leg is 15 units and the hypotenuse is 17 units, what is the length of the other leg?

• 9 units

• 8 units

• 10 units

• 12 units

How can you verify the length of a side in a right triangle using the Pythagorean theorem?

• By checking if the sum of the squares of the legs equals the square of the hypotenuse.

• By dividing the hypotenuse by the sum of the legs.

• By adding the lengths of all sides.

• By multiplying the lengths of the legs.

What is the length of segment EB if OE is 8 units and OB is 17 units?

• 15 units

• 17 units

• 8 units

• 9 units
