Given that ACE is an isosceles triangle, the measure of ∠CDB is: 55°
What is an Isosceles Triangle?
The two base angles of any isosceles triangle are always congruent to each other.
Therefore:
m∠CBD = m∠CDB
m∠CBD = 180° - 125° (supplementary angles)
m∠CBD = 55°
Therefore:
m∠CBD = m∠CDB = 55°
In summary, given that ACE is an isosceles triangle, the measure of ∠CDB is: 55°
