What is the sum of the interior angles of a triangle?

The correct answer is 'B. 180 degrees.' The sum of the interior angles of any triangle is always 180 degrees, regardless of the type of triangle. This fundamental property of triangles is crucial in geometry and applies to all triangles, including equilateral, isosceles, and scalene triangles.

What is the formula for the area of a rectangle?

In a right triangle, what is the relationship between the lengths of the sides according to the Pythagorean theorem?

The correct answer is 'A. a^2 + b^2 = c^2'. According to the Pythagorean theorem, in a right triangle, the sum of the squares of the lengths of the two legs (a and b) is equal to the square of the length of the hypotenuse (c). The other options do not represent a valid relationship for the sides of a right triangle.

What do you call a polygon with eight sides?

The correct answer is 'C. Octagon.' A polygon with eight sides is specifically referred to as an octagon. In contrast, a hexagon has six sides, a heptagon has seven sides, and a nonagon has nine sides.

What is the circumference of a circle with a radius of r?

What is the name of a three-dimensional figure with six rectangular faces?

The correct answer is 'D. Rectangular Prism.' A rectangular prism is a three-dimensional figure that has six faces, all of which are rectangles. It can also be referred to as a cuboid. The other options, such as sphere, cylinder, and cone, do not consist of six rectangular faces, making the rectangular prism the only correct choice.
