100

The sum of the interior angles of any triangle.

What is 180 degrees

100

There are these many degrees in a circle.

What is 360 degrees?

100

This is the equation of a line with slope 3 and y-intercept -2.

What is y = 3x - 2?

100

A cute little angle that measures less than 90 degrees.

What is an acute angle?

100

I don't need angles, not even a peek, just three pairs of sides is all that I seek.  If they match up from tip to base, I'll prove congruence face to face.

What is the SSS Postulate?

200

The measure of the third angle of a triangle who has a 40 degree and 65-degree angle.

What is 75-degrees? 

200

The distance around a circle is called this.

What is the circumference?

200

This is the resulting coordinate when the point (5,0) is translated 6 units up and 4 units to the right. 

 What is (9,6)?

200

A dot or an exact location

What is a Point?

200

An angle, a side, then an angle once more, in that exact order, I open the congruence door.  If your triangle matches mine just so, then congruent they are-now you know!

What is the ASA Postulate?

300

Name a triangle with all three sides equal.

What is an equilateral triangle?

300

This is the name of a line segment that connects two points on a circle but does not pass through its center.

What is a chord?

300

This is what happens when a point is reflected across the X-axis.

What is the x-coordinates remain the same, while the y-coordinates are transformed into their opposite signs.

300

A straight path that goes on infinitely in both directions.

What is a line?

300

Two sides I see, standing proud and tall, with the angles between them, I need no more at all. If they match with a twin triangle just right, I'll prove they're the same without a fight.   

What is the SAS Postulate?

400

This type of triangle, defined by having all interior angles less than 90 digress, can never contain a right or obtuse angle, yet may still be scalene or equilateral.    

What is an acute triangle?

400

This is the formula for the area of a circle.

What is A = πr²?

400

This is the formula to find the slope between two points.

What is (y₂ - y₁) / (x₂ - x₁)?

400

A straight path that has one clear origin or endpoint and the opposite end goes on forever infinitely. 

What is a ray?

400

I check two angles, then one side that's not between, Match those up, and congruence can be seen. I don't need whole shape, just a portion to view-If it fits just right, the triangles match too! 

What is the AAS Postulate?

500

This is the classification of a triangle with sides measuring 7, 24, and 25.

What is a right triangle?

500

 This is the circumference in terms of π of a circle that has a radius of 6.  

What is 12π?

500

This transformation maps (x, y) to (-x, -y)

What is a rotation of 180° about the origin?


500

A perpendicular line segment drawn from a vertex of a triangle to the opposite side. 

What is Altitude?

500

I'm picky-right triangles only need apply, with a hypotenuse and one leg, I'll verify. No need for angles or all three side-with just these two, congruence hides. 

What is the HL Postulate?
