Coordinate This!
100
Equal! Equal! Equal! This triangle is defined by having three congruent sides.
What is an equilateral triangle.
100
Adding up all the interior angles in a triangle yield this half-circular sum.
What is 180 degrees?
100
Matching up corresponding sides of one triangle with corresponding sides in another triangle is using this Triangle Congruence Postulate.
What is Side-Side-Side?
100
The longest side of a right triangle.
What is the hypotenuse?
100
If triangle MNO is congruent to XYZ, then ZY is congruent to what line segment?
What is line segment ON?
200
"Equal? Who cares!" is the motto of this triangle, which as no sides congruent.
What is a scalene triangle?
200
In an equianguar triangle, each angle in triangle ABC has this measure.
What is 60 degrees.
200
Matching two pairs of angles and one pair of included sides determines that two triangles are congruent via this theorem.
What is Angle-Side-Angle?
200
The pair of angles attached to the non-congruent side of an isosceles triangle.
What are the base angles?
200
We need precisely this many ordered pairs to determine how far apart two points are from each other.
What is two.
300
If the interior angle sum of a triangle is divided into three equal parts, this type of triangle is created.
What is an equiangular triangle.
300
There are this many exterior angles in a triangle.
What is six?
300
All we need to prove that two right triangles are congruent are these two pieces of information.
What is the hypotenuse and the leg?
300
Sides that are not the longest or the non-congruent sides in right or isosceles triangles are called these.
What are the "legs"?
300
This is the distance equation!
What is sqrt (x2-x1)^2+ (y2-y1)^2
400
If given an exterior angle in a triangle, the two interior angles not adjacent to the exterior angle are called this.
What are remote interior angles?
400
Using AAS, it is O.K. to skip over an unmarked this in order to verify that two triangles are congruent.
What is an unmarked side.
400
In any triangle, the smallest angle corresponds to this side of a triangle.
What is the smallest side?
400
In some triangles (that are flipped are rotated), the slopes may be this, but still intersect the same, making their angles the same.
What is negative/positive?
500
Only one of these types of angles is needed for a triangle to adopt its name.
What is an obtuse triangle?
500
If given that lines are parallel in triangles, you may be able to use this pair of angles to determine that they are congruent.
What are Alternate Interior Angles?
500
This commonly mistaken shortcut gives students false hope that two triangles are congruent, when in fact, it demonstrates that they are just similar.
What is Angle-Angle-Angle?
500
The name of an endpoint of two or more rays or line segments (to form a triangle) is called this in a triangle. Every triangle sports three of them.
What is a vertex?
500
When horizontal lines are given to us, we don't need to check their slope, because we know that it's this number.
