4. Equilateral and Isosceles Triangles

Continue to next subchapter

Exercise 28 Page 613

How can you move the vertices of the angles and keep the triangles congruent?

$yellow - red - blue$
$yellow - orange - red - purple - blue - green$
$orange - purple - green$
$red - orange - blue - purple - yellow - green$

Practice makes perfect

By moving the vertices of the yellow-blue-red triangle counterclockwise to the midpoint of the adjacent isosceles triangle, we can find three more triads.

As we can see, the possible triads are:

y e l l o w - r e d - b l u e y e l l o w - o r a n g e - r e d - p u r p l e - b l u e - g r e e n o r a n g e - p u r p l e - g r e e n red - orange - blue - purple - yellow - green
