Perpendicular- lines that intersect at right angles (90 degrees)
Parallel- lines in the same plane that never cross or interest
Interescting- lines that cross at any angle
Perpendicular bisector- a line that divides a line segment in half at a right angle
Angle bisector- a line that divides an angle into two equal parts
Acute angle- an angle at less than 90 degrees
Obtuse angle- an angle more than 90 degrees
Right angle- an angle exactly 90 degrees
- the formula for the area of a triangle is base times height divided by 2.
- the formula for the area of a parallelogram is base times height.
If the base of a parallelogram is 50m and the height is 20m, what is the area?
A= 50 X 20
A = 1000 m 2
Converting fractions, decimals and percents...
-Remember that fractions are out of any whole number.
-Percents are out of 100.
-Decimals are out of 1.
Sorry for not including any pictures, my computer is messed up at the moment..
