Practice Examination - 1st Semester Geometry

Front

What is the measure of \( \angle U \) if it is given that the angle measures are 110°, 35°, 180°, and 17.5°?

Back

The measure of \( \angle U \) is 35°.

Front

What point of concurrency is determined by the 3 angle bisectors of any triangle?

Back

The point of concurrency determined by the 3 angle bisectors of any triangle is the Incenter.

Front

Identify the type of quadrilateral with vertices A(3, -4), B(3, -1), C(0, -1), D(0, -4).

Back

The quadrilateral is a Square.

Front

What is the result of reflecting a point across the x-axis?

Back

The reflection across the x-axis changes the sign of the y-coordinate.

Front

Calculate the area of a composite shape with an area of 112cm², 24cm², 136cm², and 2688cm².

Back

The area of the composite shape is 136cm².

Front

Define the Incenter of a triangle.

Back

The Incenter is the point where the angle bisectors of a triangle intersect, and it is equidistant from all sides of the triangle.

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is given by the formula: \( A = l \times w \), where \( l \) is the length and \( w \) is the width.

Front

What is the definition of a parallelogram?

Back

A parallelogram is a quadrilateral with opposite sides that are both equal in length and parallel.

Front

What is the relationship between the angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180°.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: \( A = \frac{1}{2} \times b \times h \), where \( b \) is the base and \( h \) is the height.
