What theorem is being shown figure 1?

• If two lines intersect, then they intersect at exactly on point.

• If a point lies outside the line, then exactly one plane contains both the line and the point.

• If two lines interest, then exactly one plane contains both line.

• The intersection of two plane is a line.

Which of the following defines congruent triangles?

• Two triangles are congruent if and only if the corresponding sides are congruent.

• Two triangles are congruent if and only if the corresponding angles are congruent.

• Two triangles are congruent if and only if the corresponding sides and the corresponding angles are congruent.

• Two triangles are congruent if and only if no corresponding sides and no corresponding angles are congruent.
