MO MAP Grade 8 Geometry Practice — Sports Academy Games

What the test measures

Geometry skills

Understand congruence and similarity using physical models, transparencies, or geometry software
Understand and apply the Pythagorean Theorem
Solve real-world and mathematical problems involving volume of cylinders, cones, and spheres
Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures

Standards basis

Missouri Learning Standards (Mathematics K-5 and Mathematics 6-12; revised standards approved April 19, 2016) — Missouri

How the MO MAP reports it

Missouri’s MAP math is built from the Missouri Learning Standards and the state’s item specifications, not from a separate national testing framework. The standards are closely CCSS-aligned in structure, with grade-level and course-level domains used as the native reporting/coverage structure.

Blueprint & weighting

Missouri publishes grade-level and EOC blueprints, but the accessible official pages in this pass did not expose the domain-by-domain percentage tables. The assessment page states that item specifications organize expectations by domains/strands and that blueprints are available for grade-level and EOC assessments.

A cylinder has radius $2$ and height $3$ . Using $\pi = 3$ , what is its volume?

$V = \pi r^2 h = 3 \times 4 \times 3 = 36$ .

The distance between $(0, 0)$ and $(6, 8)$ is $d$ . What is $d^{2}$ ?

$d^{2} = 6^2 + 8^2 = 36 + 64 = 100$ .

In $\triangle JKL$ , $\angle J$ and $\angle L$ are congruent. The measure of each of these angles is $61.7^{\circ}$ . What is the measure of $\angle K$ ?

The two congruent angles total $2 \times 61.7^{\circ} = 123.4^{\circ}$ , so $\angle K = 180^{\circ} - 123.4^{\circ} = 56.6^{\circ}$ .

What is the sum of the interior angles of a decagon?

A decagon has $10$ sides: $(10-2) \times 180 = 1440°$ .

In a right triangle, one leg is $9$ feet and the hypotenuse is $41$ feet. How long is the other leg?

Let the missing leg be $x$ . Then $x^{2} + 9^{2} = 41^{2}$ , so $x^{2} = 41^{2} - 9^{2} = 1{,}681 - 81 = 1{,}600$ and $x = \sqrt{1{,}600} = 40$ .

One leg of a right triangle is $10$ and the hypotenuse is $26$ . What is the missing leg?

$26^{2} - 10^{2} = 676 - 100 = 576$ , so the missing leg is $\sqrt{576} = 24\textsf{.}$

Practice playeasy

A $26$ -meter guy wire runs from the top of a pole to a stake $24$ meters from the pole's base. How tall is the pole?

The wire is the hypotenuse: $26^{2} - 24^{2} = 676 - 576 = 100$ , so the pole is $\sqrt{100} = 10$ meters tall.

A rectangle has length $8$ centimeters and area $120$ square centimeters. What is the length of a diagonal of the rectangle, in centimeters?

Area $A = \ell w$ , so $120 = 8w$ and $w = 15$ . The diagonal is the hypotenuse of a right triangle with legs $8$ and $15$ : $\sqrt{8^2 + 15^2} = \sqrt{64 + 225} = \sqrt{289} = 17\text{ cm}\textsf{.}$
