MAFS.4.MD Measurement and Data
MAFS.4.G Geometry
Practice-Test
MAFS.4.MD.3.5 Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and
understand concepts of angle measurement:
a.
b.
An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the
fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a
circle is called a “one-degree angle,” and can be used to measure angles.
An angle that turns through n one-degree angles is said to have an angle measure of n degrees.
. MAFS.4.MD.3.6 Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.
MAFS.4.MD.3.7 Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure
of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a
diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure.
MAFS.4.G.1.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify
these in two-dimensional figures.

c) Ray DF is the side of Angle 1.
d) The vertex of Angle 1 is E and the vertex of Angle 2 is I.
Question 2 [MAFS.4. MD.3.7] Multi-Select
A semi-circle is split into four equal angles as
shown.
The sum of the angle measures is 180º.
Which equation can be used to find o?
a. 180 ÷ 4 = o
b. 180 − 4 = o
c. 180 + 4 = o
d. 180 × 4 = o
