m∠ A ? = m∠ T Recall that, in similar triangles, the measures of corresponding angles are equal.
Since the angles are corresponding, they must be congruent. ∠ A ≅ ∠ T This means that, yes, they have the same measurement. ∠ A ≅ ∠ T ⇕ m∠ A = m∠ T
Let's assume that x is the value of the ratios, then we have the following scale of our ratio of the sides.
Side in △ ABC | Corresponding Side in △ TUV | Proportion |
---|---|---|
AB | TU | AB= TUx |
BC | UV | BC= UVx |
CA | VT | CA= VTx |
Substitute expressions
Factor out x
x= 1
a * 1=a
We are asked to determine whether the measures of the given ratios are the same. BC/UV and AC/TV, Recall that in similar figures all the corresponding side lengths keep the same proportions. Notice that BC and UV, as well as AC and TV, are corresponding sides.
Therefore, yes, both quotients will have the same proportion and will measure the same.
