20
Q

A/an ______ triangle is a triangle with three acute angles, which are angles that measure between 0° and 90°.

A

Acute.

21
Q

A/an _________ triangle is a triangle with three sides of equal length, and three angles that are all congruent and equal to 60°.

A

Equilateral.

22
Q

A/an __________ triangle is a triangle in which all three sides are in different lengths, and all three angles are of different measures. However, the sum of all the interior angles is always equal to 180 degrees.

A

Scalene.

23
Q

A/an _________ triangle is a triangle with two sides of equal length, also known as the legs, and two angles that are equal. The third side of an isosceles triangle is called the base. The angles opposite the two equal sides are also equal

A

Isosceles.

24
Q

If the square of the length of the longest side of a triangle is equal to the sum of the squares of the lengths of the other two sides, then this is considered a/an _________ triangle.

A

Right.

Q

A/an ____________ triangle is a triangle with one angle that measures more than 90° but less than 180°. The side opposite the obtuse angle is the longest side, and the sum of the remaining two angles is less than 90°.

A

Obtuse.

26
Q

True or false? An obtuse triangle always has a right angle.

A

False - it NEVER has a right angle.

27
Q

A/an __________ is a four-sided closed figure with two parallel sides and two non-parallel sides.

A

Trapezoid.

28
Q

A trapezoid is also called a __________.

A

Trapezium.

29
Q

The word ___________ comes from the Greek trapeza meaning “table” and -oeides meaning “shaped.

A

Trapezoid.

30
Q

Area of a trapezoid.

A

A = (a + b)/2 x h.

31
Q

A/an _________ is a 3-dimensional figure that is perfectly round and equidistant from a single point in space.

A

Sphere.

32
Q

True or false? The fixed point is called the center of the sphere, and the distance from the center to the surface is called the radius.

A

True.

33
Q

True or false? The maximum distance from one side of the sphere to another is called the demogorgon.

A

False - diameter.

34
Q

What is the formula for the surface area of a prism?

A

The surface area of a prism is given as S = (2 × Base Area) + (Base perimeter × height) where “S” is the surface area of the prism.

35
Q
