Question
Answer
All right angles are congruent   Right Angles Congruence Theorem  
🗑
If a triangle is equiangular, then the triangle is equilateral   Corollary to the Base Angles Converse  
🗑
If the corresponding side lengths of two triangles are proportional, then the triangles are similar   Side-Side-Side Similarity (SSS Sim)  
🗑
Vertical Angles are congruent   Vertical Angles Congruence Theorem  
🗑
If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent   Alternate Interior Angles Congruent  
🗑
If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent   Alternate Exterior Angles Congruent  
🗑
If two parallel lines are cut by a transversal, then the consecutive interior (co-interior) angles are supplementary   Consecutive Interior (Co-Interior) Angles Supplementary  
🗑
If two lines are cut by a transversal and alternate interior angles are congruent, then the two lines are parallel   Alternate Interior Angles Converse  
🗑
If two lines are cut by a transversal and alternate exterior angles are congruent, then the two lines are parallel   Alternate Exterior Angles Converse  
🗑
If two lines are cut by a transversal and co-interior angles are supplementary, then the two lines are parallel   Co-Interior Angles Converse  
🗑
If two lines are parallel to the same line, then they are parallel to each other   Transitive for Parallel Lines  
🗑
The sum of the measures of the interior angles of a triangle is 180 degrees   Triangle Sum Theorem  
🗑
The measure of an exterior angle of a triangle is equal to the sum of the measures of the two nonadjacent interior angles   Exterior Angle Theorem  
🗑
If two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths   Perimeters of Similar Polygons Theorem  
🗑
If an angle of one triangle is congruent to an angle of a second triangle and the lengths of the sides including these angles are proportional, then the triangles are similar   Side-Angle-Side Similarity (SAS Sim)  
🗑
If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of a second triangle, then the two triangles are congruent   Angle-Angle-Side (AAS) Congruence Theorem  
🗑
If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the two triangles are congruent   Angle-Side-Angle (ASA) Congruence Theorem  
🗑
If two sides of a triangle are congruent, then the angles opposite the sides are congruent   Base Angles Theorem  
🗑
If a triangle is equilateral, then the triangle is equiangular   Corollary to the Base Angles Theorem

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
