To determine the measure of angle ACD, more information is needed, such as the context of the geometric figure, any given angles, or relevant side lengths. Without specific details or a diagram, it's impossible to provide an accurate measure for angle ACD. Please provide additional information for clarification.

What is the proof that equiangular triangle is also called equilateral triangle?
Label the triangle ABC. Draw the bisector of angle A to meet BC at D. Then in triangles ABD and ACD, angle ABD = angle ACD (equiangular triangle) angle BAD = angle CAD (AD is angle bisector) so angle ADB = angle ACD (third angle of triangles). Also AD is common. So, by ASA, triangle ABD is congruent to triangle ACD and therefore AB = AC. By drawing the bisector of angle B, it can be shown that AB = BC. Therefore, AB = BC = AC ie the triangle is equilateral.
Write a two column proof given line cb bisects angle and and acd prove triangle abc is congruent to triangle dbc?
To prove that triangle ABC is congruent to triangle DBC given that line CB bisects angle ACD, we can use the Angle-Side-Angle (ASA) postulate. Proof: | Statements | Reasons | |---------------------------------------------------|------------------------------------------| | 1. CB bisects angle ACD. | 1. Given. | | 2. Angle ACB ≅ Angle DCB. | 2. Definition of angle bisector. | | 3. Line CB is common to both triangles ABC and DBC. | 3. Common side. | | 4. Triangle ABC ≅ Triangle DBC. | 4. ASA Postulate (Angle ACB ≅ Angle DCB, CB is common, and Angle ACD is shared). |

How do i prove if the base angles of a triangle are congruent then the triangle is isosceles?
Suppose you have triangle ABC with base BC, and angle B = angle C. Draw the altitude AD.Considers triangles ABD and ACDangle ABD = angle ACD (given)angle ADB = 90 deg = angle ACDtherefore angle BAD = angle CADAlso the side AD is common to the two triangles.Therefore triangle ABD is congruent to triangle ACD (ASA) and so AB = AC.That is, triangle ABC is isosceles.
