what is an inscribed angle?
an angle by 2 chords thats on the edge of a circle (anything similar to the meaning still get a point!)
what is an axis of rotation?
a line in which a 2d shape rotates around (anything similar to the meaning still get a point!)
what is an complementary?
its two angles are complementary to each other if their measures add up to 90 degrees (anything similar to the meaning still get a point!)
what all transformations have in common?
they have somewhere to move. they involve a beginning, a process and an end point (anything similar to the meaning still get a point!)
triangle CAT is congruent triangle XYZ, which statement is true?
1. <A congruent to <Y
2. line CA congruent to XZ
3. <T congruent to <X
its 1!
what is a point of tangency?
a line is tangent if and only if it is perpendicular to the radius drawn to the point of intersection (anything similar to the meaning still get a point!)
what is a volume?
the amount of space inside a 3d shape (anything similar to the meaning still get a point!)
BONUS QUESTION!! (+100 if won, -100 if lost) if standing on a bridge 120 from the bottom of the building and have to look up 45 degree angle to see the top, how tall is the building? (hint hint: sin, cos)
x = 120 :p
(x,y) - (x+10, y - 4)
A= (-11,6)
A= (-1,2)
if triangle YET is congruent to triangle RUT, which statement is always true?
1. <TEY is congruent to <URT
2. line ET is congruent to line UT
3. <YTE is congruent to <TUR
its 2!
BONUS QUESTION!! (+100 if won, -100 if lost) what is a circumference?
the distance around a shape (sort of like the perimeter)
what is a cylinder?
a 3d shape with two congruent and parallel circle bases, formed by connecting one base to the other (anything similar to the meaning still get a point!)
whats soh-cah-toa ?
sin, cos, tan (anything similar to the meaning still get a point!)
BONUS QUESTION!! (+100 if won, -100 if lost) whats a median?
a median of a triangle is a line segment that connect a vertex to the midpoint of line (anything similar to the meaning still get a point!)
which condition does not prove that two triangles are congruent
1. SAS congruent to SAS
2. ASA congruent to ASA
3. SSA congruent to SSA
its 3!
what is a circumscribed
a polygon is circumscribed if it fits inside the circle and every verticle of the polygon is on the circle (anything similar to the meaning still get a point!)
BONUS QUESTION!! (+100 if won, -100 if lost) what are 3d shapes made from?
translation and dilation
where does your adjacent go in a triangle?
at the bottom of your triangle
what transformation do you think goes with this rule?
(x,y) --> (-x,y)
reflection!
just a bonus, yall got it
yippie
what is a cyclic quadrilateral?
a quadrilateral whose verticle (points) all line on the same circle (anything similar to the meaning still get a point!)
what is a pyramid?
a 3d figure with one unique base and all the face are triangles that meet at a point called the apex (anything similar to the meaning still get a point!)
whats a slope?
rise / run
(4,2) with 3 units up
(4,5)

1. AAA
2. SAS
3.SSS
4.AAS
