Geometry EOC Review 1

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a postulate that states if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What additional information is required for two triangles to be congruent by SSS?

Back

For two triangles to be congruent by SSS (Side-Side-Side), the lengths of all three sides of one triangle must be equal to the lengths of all three sides of the other triangle.

Front

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

Back

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

Front

What is the measure of arc QR if the options are 106, 85, 113, 78?

Back

The measure of arc QR is 78.

Front

Calculate the probability that a point selected randomly inside a square with a side length of 10 cm is located within 2 cm of any of the sides.

Back

The probability is 16/25.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a postulate that states if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the definition of a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape, including translations, rotations, reflections, and dilations.

Front

What is the difference between a reflection and a rotation?

Back

A reflection flips a shape over a line (mirror image), while a rotation turns a shape around a fixed point.

Front

What is the formula for the area of a square?

Back

The area of a square is calculated as A = side², where 'side' is the length of one side of the square.

Front

What is the relationship between the angles and sides in an ASA triangle?

Back

In an ASA triangle, if two angles and the included side are known, the third angle can be found using the fact that the sum of angles in a triangle is 180 degrees.
