Day 6: Similar Triangles
Similar triangles work the same way as any other shape, but you can also use angles with triangles.
If the angles are the same, the triangles are similar.
Matching amounts of arcs mean that they are the same angle. All of the above are similar.
Even though the shapes aren't the same size and may be rotated, the shapes, like the ones above, will most likely be similar.
Quiz Time!
1. Are the triangles similar?
2. What is the measure of the missing angles?
3. Are the triangles similar?
Key:
1. The triangles are similar because they share the same angles
2. The missing angles are 70 and 80
3. The triangles are similar because the two edges are parallel.
