Transcript of TAKS Review

TAKS Review Percent is out of 100 interior angles of a triangle equal 180 Triangles are named by there angles and sides Named by side:
Scalene- NO sides equal
Isosceles - TWO sides equal
Equilateral- ALL sides equal Named by angles:
Right - One 90 degree angle
Acute - All angles less then 90
Obtuse - One angle greater then 90 Change a fraction to a
decimal DIVIDE! (numerator
divded by denomenator) Change Percent to Decimal or
Decimal to Percent, move decimal 2 places.
Angles in quadrilateral equal 360 Trapezoid - One set of parallel sides. Parallelogram- 2 sets of parallel sides, opposite sides and angles congruent. Rhombus- 2 sets of parallel sides,
all sides congruent Rectangle- 2 sets of parallel sides,
opposite sides congruent, 4 right angles Square- All sides and angles congruent (angles equal 90) Supplementary - 2 angles 180 degrees
Complementary- 2 angles 90 degrees Perimeter- distance around, units no exponent Area - the space something covers, units squared Volume- how much it will hold, units to the 3rd power USE YOUR MATH CHART!!! TAKE YOUR TIME! IF YOU GET TO A PROBLEM
AND YOU DON'T KNOW HOW
TO DO IT, SKIP IT, DO NOT GET
FRUSTRATED!!!!!!!! When working a problem
with a pattern, the pattern
is always the number you
mulitply in the equation.
If you have no idea, plug in
1, 2, 3 into the equations and
find your pattern. Tax, commission, discount problems you
can use a ratio or multiply by the percent,
just don't forget to add or subtract
it to the original. Percent of change: amount of change over original Be careful for the word NOT! When looking at a picture of something squared or square root, the picture must be a SQUARE!!! 3-D shapes are named by their bases Pyramid - has 1 base
Prism- 2 bases Mean (average) - add all up and divide by how many there are
Mode- Number that occurs the most
Median- Number in the middle
Range- Greatest minus Least Translation - slide
Reflection - flip
Rotation - turn
DO NOT PICK TESSELLATION When adding or subtracting
decimals line them up. Adding and Subtracting Fractions - common denmenator
Multiplying Fractions- Top x Top Bottom X Bottom
Dividing Fractions- Flip the second and muliply
(Multiply and Divide- Change mixed numbers into improper fractions and whole numbers put over 1) Circumference - distance around Coordinate Grid (x, y) Quadrant I Quadrant II Quadrant III Quadrant IV Order of Operation
Use it ALWAYS!

Parantheses
Exponents
Multiply/Divide
Add/Subtract If you are solving an equation and are lost, plug in your answer choices into the equation!!! Similar Figures:
Same Shape
Angles Congruent
Sides Proportional
Different SIZE
Similar Figures:
Sides proportional, so if missing side
use proportions to solve!!!
Integers on number line:
The bottom line tells 1st number, second/third line count to see how far you add. Final stopping point is answer NOT part of expression. Adding Integers: signs same add keep signs
signs different find the difference
(keep sign of larger number) Subtracting Integers-
Change minus to plus and sign of second number
Multiply and Divide Integers-
Same signs positive
Different signs negative

P N N YOU CAN DO THIS, HAVE CONFIDENCE! YOU ARE ALL PASSING 8TH GRADE MATH,
THERE IS NO REASON YOU CAN NOT PASS THE 7TH GRADE TAKS TEST! BELIEVE
IN YOURSELF!!!!
