Polygons
Moving a figure across a distance without changing size or orientation.
What is translation?
((base1+base2)/2) (h)
What is the area of a trapezoid?
A triangle with no congruent sides.
What is Scalene?
H2-L2=L2
What is the Pythagorean Theorem?
APT or states that a) Opposite sides of a rhombus or trapezoid are congruent b) Already Proven Theorem c) Opposite sides of a rectangle/parallelogram are congruent.
What is Opposite sides of a rectangle/parallelogram are congruent?
A line or line segment that is perpendicular to another line segment through its midpoint.
What is perpendicular bisector?
2πr 2+ 2πrh
What is the surface area of a cylinder?
True or False: Two triangles are similar if the (hyp of small triangle)/(hyp of large triangle) = (LL of large triangle)/(LL of small triangle)
What is False. 200 extra points if you can share one way to show a correct ratio for similar triangles.
The measure of an inscribed angle in a circle compared to the measure of the intercepted arc.
What is one half the measure of the intercepted arc?
True or False: LL Postulate can be used to prove any 2 triangles congruent.
What is False?
The sum of interior angles of a quadrilateral.
What is 360 degrees?
1/3 area of base(B) x h
What is the volume of a pyramid or a cone?
The hypotenuse of a 30-60-90 triangle.
2 times the short leg
True or False: The inverse of secant(sec) is adjacent/hypotenuse.
What is True? For 100 more points, what is the Trig function for adj/hyp?
True or False: CPCTRC means Corresponding parts of congruent triangles are corresponding.
What is False? Name the correct words for an extra 200 points.
The sum of the exterior angles of 3 regular polygons.
What is 3x360 degrees?
(1/2 short axis)(1/2 long axis)(π)
What is the area of an ellipse?
Hypotenuse / Opposite
What is cosecant (csc)?
True or False: 1 - cos2 = (opp/hyp)2
What is True?
True or False: Proving 2 right triangles congruent does not require knowing the measure of an angle other than the right angle. Explain why or why not.
True and False. Right Triangles already have matching right angles, so if you prove 2 sets of legs congruent or the hypotenuse and one leg congruent, then you have congruent triangles. If not, you need an angle in addition to a leg or hypotenuse to prove congruent triangles.
The sum of the interior angles of 2 congruent regular polygons.
What is 2(N-2) x 180 degrees? (N = number of sides)
1/2 the measure of the intercepted arc
What is the measure of the inscribed angle?
The inverse of sine.
What is what is cosecant or hyp/opp?
True or False: The inverse of tangent is opp/adj
What is False? For 100 more points, what is the inverse of tangent?
True or False: Similar triangles have corresponding sides congruent.
What is False? For an extra 500 points, explain one way to prove that 2 triangles are similar.
