Right Triangles
Isosceles and Equilateral Triangles
100

All angles measure less than 90 degrees.

What is Acute?

100

Number of angles in a triangle.

What is 3 angles

100

It states if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.

What is HL?

100

True or False. 

All right triangles can be proven congruent with HL.

What is false?

100
Has two congruent sides called legs.
What is Isosceles Triangle
200
Two equal sides and angles
What is Isosceles
200
The value of all three angles in a triangle added together.
What is 180 degrees
200
If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
What is SAS
200
The sum of the two acute angles in a right triangle.
What is 90 degrees
200
All three sides are congruent.
What is Equilateral Triangle
300
All sides and angles are equal.
What is Equilateral
300

Find the missing angle in the triangle with angles of:

56 degrees and 107 degrees.

What is 17 degrees?

300
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then these two triangles are congruent.
What is ASA
300

The side across the right angle in a right triangle.

What is hypotenuse?

300

The two congruent sides on a isosceles triangle are called:

What is legs?

400
Has an angle whose measurement is greater then 90 degrees.
What is Obtuse
400
The little box in the corner of a triangle.
What is 90 degrees.
400
If two angles and the non-included side one triangle are congruent to two angles and the non-included angle of another triangle, then these two triangles are congruent.
What is AAS
400

The sides that are not the hypotenuse are called:

What are legs?

400

The side opposite of the vertex.

What is a base?

500

A triangles with no congruent sides or angles

What is scalene?

500
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
What is Exterior Angle Theorem
500
If three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
What is SSS
500

It states that the sum of the squares of the legs of a right triangle equals the square of the hypotenuse of a right triangle.

What is Pythagorean Theorem?

500

The theory that states if two sides of a triangle are congruent, then the angles opposite of those sides are congruent.
