Exploring Triangles
#1: True or False
If two angles in one triangle are each congruent to two angles in another triangle, then their
third angles must be congruent.
Move the sliders.
#2: True or False
If exactly one angle in one triangle is congruent to one angle in another triangle, then the triangles are similar.
Move the sliders.
#3: True or False
If all the corresponding angles in two triangles are congruent, then the triangles are similar.
Move the sliders.
#4: True or False
Every triangle that has two congruent sides always has two congruent angles.
Move B and E and the sliders.
#5: True or False
If two sides in a triangle are proportional to two corresponding sides in another triangle, then the triangles are similar.
Move the sliders to make two of the sides in one triangle proportional to two in the other.
#6: True or False
If two triangles have all their corresponding sides proportional, then the triangles are similar.
