How the ATLAS reports it

Arkansas’s statewide assessment system is ATLAS, which the ADE page says began serving in spring 2024. The official public page does not publish a math blueprint there, so the most defensible coverage map is the Arkansas math standards structure that ATLAS is aligned to.

Blueprint & weighting

ATLAS uses the Independent / state-specific framework (by grade domains structure).

In a $30^{\circ}$ - $60^{\circ}$ - $90^{\circ}$ triangle, the short leg is $10\textsf{.}$ What is the hypotenuse?

In a $30^{\circ}$ - $60^{\circ}$ - $90^{\circ}$ triangle, the hypotenuse is twice the short leg: $2 \times 10 = 20\textsf{.}$

In a $45$ - $45$ - $90$ triangle one leg is $15$ . What is the other leg?

Both legs of a $45$ - $45$ - $90$ triangle are equal, so the other leg is $15$ .

Two parallel lines are cut by a transversal. Same-side interior angles measure $(6x-5)°$ and $(4x+15)°$ . What is the value of $x$ ?

Same-side interior angles are supplementary: $(6x-5)+(4x+15)=180$ , so $10x+10=180$ and $x=17$ .

Which transformation takes a line segment over a perpendicular bisector so that the segment maps directly onto itself?

A reflection is a rigid transformation that maps the points from a preimage, over a line of reflection, to the points of an image that are equidistant to the line. In this example, that line is the perpendicular bisector of a line segment from a point to its image, so the segment maps onto itself.

In a $30^{\circ}$ - $60^{\circ}$ - $90^{\circ}$ triangle, the hypotenuse is $22\textsf{.}$ What is the short leg?

In a $30^{\circ}$ - $60^{\circ}$ - $90^{\circ}$ triangle, the short leg is half the hypotenuse: $\dfrac{22}{2} = 11\textsf{.}$

In a $30$ - $60$ - $90$ triangle the hypotenuse is $14$ . What is the short leg?

The short leg is half the hypotenuse: $\dfrac{14}{2} = 7$ .

Practice playeasy

Two parallel lines are cut by a transversal. A linear pair of adjacent angles measure $(5x+10)°$ and $(3x+50)°$ . What is the measure of the larger angle?

A linear pair is supplementary: $(5x+10)+(3x+50)=180$ , so $8x+60=180$ and $x=15$ . The angles are $85°$ and $95°$ , so the larger is $95°$ .

Practice playeasy

Which transformation turns a figure $80^{\circ}$ around a fixed point so that all points remain equidistant from that point?

A rotation is a rigid transformation that turns a figure around a fixed point, called a center of rotation, by a specific angle in a specific direction. All points remain equidistant from the center of rotation, keeping the image congruent to the preimage. In this example, that angle is $80^{\circ}\textsf{.}$
