Which types of triangles will always have at least two sides of equal length?
equilateral and right |
|
isosceles and right |
|
equilateral, isosceles and right |
|
equilateral and isosceles |
An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.
A(n) __________ is two expressions separated by an equal sign.
formula |
|
expression |
|
equation |
|
problem |
An equation is two expressions separated by an equal sign. The key to solving equations is to repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
If the length of AB equals the length of BD, point B __________ this line segment.
trisects |
|
midpoints |
|
intersects |
|
bisects |
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.
Solve for y:
-5y - 7 = -6 - 6y
| -1\(\frac{2}{5}\) | |
| 1 | |
| -9 | |
| 1\(\frac{2}{5}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
-5y - 7 = -6 - 6y
-5y = -6 - 6y + 7
-5y + 6y = -6 + 7
y = 1
The formula for the area of a circle is which of the following?
a = π d2 |
|
a = π r |
|
a = π d |
|
a = π r2 |
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.
