If the length of AB equals the length of BD, point B __________ this line segment.
bisects |
|
midpoints |
|
intersects |
|
trisects |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
If side x = 5cm, side y = 8cm, and side z = 12cm what is the perimeter of this triangle?
| 30cm | |
| 29cm | |
| 23cm | |
| 25cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 5cm + 8cm + 12cm = 25cm
What is the area of a circle with a diameter of 8?
| 4π | |
| 16π | |
| 8π | |
| 9π |
The formula for area is πr2. Radius is circle \( \frac{diameter}{2} \):
r = \( \frac{d}{2} \)
r = \( \frac{8}{2} \)
r = 4
a = πr2
a = π(42)
a = 16π
The formula for the area of a circle is which of the following?
c = π d2 |
|
c = π r |
|
c = π r2 |
|
c = π d |
The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)2 : a = π r2.
A(n) __________ is to a parallelogram as a square is to a rectangle.
trapezoid |
|
quadrilateral |
|
triangle |
|
rhombus |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
