If the base of this triangle is 5 and the height is 4, what is the area?
| 98 | |
| 36 | |
| 10 | |
| 60 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 5 x 4 = \( \frac{20}{2} \) = 10
A right angle measures:
180° |
|
360° |
|
90° |
|
45° |
A right angle measures 90 degrees and is the intersection of two perpendicular lines. In diagrams, a right angle is indicated by a small box completing a square with the perpendicular lines.

| 7 | |
| 6 | |
| 27 | |
| 14 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 6 x 1
a = 6

On this circle, line segment AB is the:
circumference |
|
radius |
|
diameter |
|
chord |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
