Similar Figures Direct Measurement

Tell whether the figures are similar.

• Yes; the triangles are similar because the angles are equal and the sides are proportional.

• Yes; the triangles are similar because the angles and sides are proportional.

• No; the triangles are not similar because the angles are not equal and the sides are not proportional.

• No; the triangles are not similar because the angles are equal but the sides are not proportional.
