Answer:
Sum of all these angle is 180° we can construct one triangle only.
Step-by-step explanation:
Given : You’re given three angle measurements of 30°, 70°, and 80°.
To find : How many triangles can you construct using these measurements.
Solution : We have given the angle 30°, 70°, and 80°.
By the angle sum property : sum of all angle of a triangle is 180°.
30° +70° + 80° = 180°.
Therefore, Sum of all these angle is 180° we can construct one triangle only.
