Transformations
How a figure moves when it is being translated.
What is, left, right, up and down?
A pair of angles that are on the same side of the transversal that lie in between the parallel lines.
What is, Consecutive Interior/ Same-Side Interior Angles?
What is the formula for cosine?
What is adjacent/ hypotenuse?
What is the difference between central and inscribed angles?
The two things that you look for when trying to determine whether or not 2 lines are parallel.
What is, lines that don't intersect, and equal slopes?
Figure ABCD has the coordinates A(5,-6), B(7,3) C(-2,-3), and D(-1,-2), and will move 4 units to the right, and 3 units down. Its new coordinates are:
What is A'(9,-9), B'(11,0), C'(2,-6), D'(3,-5)?
True or False: The parallel lines that are being intersected by the diagonal line in a transversal, are called "transversals."
What is, False?
How do you find the measure of an inscribed angle if you're given the measure of the intercepted arc?
What is divide by 2?
A perpendicular slope is always the...
What is, the negative reciprocal?
Reflect the point (-3, 4) over the y-axis.
What is (3, 4)?
TRUE or FALSE: The sum of 2 supplementary angles and 2 complementary adds up to 450 degrees.
What is, False? (it adds up to 540)
If the hypotenuse of a triangle is 8, the opposite leg is 7, and the adjacent leg is 6, find tangentθ.
What is tanθ= 7/6?
If an angle is inscribed in a semicircle, what is the measure of the angle?
What is 90°?
Find the negative reciprocals of each slope:
1. y = -3x + 5
2. y = -5/3x + 4
3. y = 2/8x + 6
4. y = 4/5x + 9
What is,
1/3 , 3/5 , -4 , and -5/4?
Rotate the point (6, -7) 180° about the origin.
What is (-6, 7)?
TRUE or FALSE: Adding up all the angle measures in a transversal and dividing it by 360 will reveal all congruent angles in the transversal.
What is, False?
Given a hypotenuse of 12 and a leg of 6, find the length of the missing leg.
What is 10.4?
If the first chord contains a=6 and b=7. The second chord contains c=4 and d is unknown. Using the chord product theorem, find the length of the chord CD.
What is 14.5?
Determine if the lines are parallel, perpendicular, or neither:
y= 14x + 7 , 8x + 4y = 16
What is, neither?
Reflect the point (1, -5) over the x-axis, then translate by the rule (x, y)→ (x-3, y+2).
In a transversal, the top right angle measures 60°. What is the measure of the bottom left angle? What are these angles called?
What is alternate exterior angles, bottom left= 60°.
If the length of an opposite leg is 4, the length of the adjacent leg is 6, and the hypotenuse is unknown, find sineθ. Round to nearest tenth.
What is sinθ= 4/7.2?
Using the formula for the area of a sector, find the area of the sector when the diameter of the circle is 14 and the arc measures 50°? (Use 3.14 as pi Π)
What is 21.37in.3?
Determine whether or not the lines are perpendicular:
y = 6/7x + 3 and 3y + 2x = 8
What is, the lines are not perpendicular?
