WEEK 2C(GEOMETRY)

Front

What are the coordinates of point B' after rotating point B(6,5) 180° about the origin?

Back

(0, 0)

Front

What does the SSS triangle congruence theorem state?

Back

If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What does the SAS triangle congruence theorem state?

Back

If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

Describe the transformation: Reflect across the x-axis and then rotate -90 degrees around the origin.

Back

This transformation first flips the figure over the x-axis and then rotates it 90 degrees clockwise.

Front

If point X(1, 4) is translated 3 units to the left and 9 units down, what are the new coordinates of X'?

Back

(-2, -5)

Front

What is the effect of a 90-degree rotation about the origin on the point (x, y)?

Back

The new coordinates will be (-y, x).

Front

What is the effect of reflecting a point across the y-axis?

Back

The x-coordinate changes sign, resulting in the point (-x, y).

Front

What is the effect of translating a point (x, y) 5 units up?

Back

The new coordinates will be (x, y + 5).

Front

What is the effect of a 180-degree rotation about the origin on the point (x, y)?

Back

The new coordinates will be (-x, -y).

Front

What does the AAS triangle congruence theorem state?

Back

If two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, then the triangles are congruent.
