Similair Triangles

Are these triangles similar?
1. Yes, they are because of angle, angle
2. No, they are not because they do not have congruent sides.
3. Yes, because of ASA ( Angle side Angle)
4. No, they are not because of angle angle.
Why are these two triangles similiar?
1. ASA (Angle side Angle)
2. AA (angle, angle)
3. SAS ( side angle side)
4. SSS (side side side)

In this problem you have a rectangle that contains an isosceles triangle. There are two triangles that are shaded in. Are these two triangles similar triangles?
1. Yes, because of side side side
2. No, because of side angle side
3. Yes, because they have two angles the same. Angle angle
4. No, because the isosceles triangle makes on triangle smaller than the other triangle.
