What is the length of segment \(DF\)?
Triangle A B C and D E F. Measurements are as follows: A B is 8, A C is 6, angle A is 68 degrees, angle B is 44 degrees, D E is 18, angle D is 68 degrees,and angle F is 44 degrees.
In triangle \(ABC\), angle \(A\) is 35º and angle \(B\) is 20º. Select all triangles that are similar to triangle \(ABC\).
triangle \(DEF\) where angle \(D\) is 35º and angle \(E\) is 20º
triangle \(GHI\) where angle \(G\) is 35º and angle \(I\) is 30º
triangle \(JKL\) where angle \(J\) is 35º and angle \(L\) is 125º
triangle \(MNO\) where angle \(N\) is 20º and angle \(O\) is 125º
triangle \(PQR\) where angle \(Q\) is 20º and angle \(R\) is 30º
Decide whether triangles \(ABC\) and \(DEC\) are similar. Explain or show your reasoning.
Must these parallelograms be similar? Explain your reasoning.
Quadrilaterals \(Q\) and \(P\) are similar.
What is the scale factor of the dilation that takes \(P\) to \(Q\)?
\(\frac35\)
\(\frac45\)
\(\frac54\)
\(\frac53\)
The circle centered at \(Q\) is a scaled copy of the circle centered at \(R\).
