MathBrush is being tested with a few parent groups, and every solution on the site is open to them — one household, all children. If you were given a code, it goes in once and this device remembers it.

65 worked examples are free without a code, two from every pattern. No account, either way.
Mark the shape property first, then subtract known angles from the relevant total.
In this one. Mark the degree before drawing the second ray, then check from the same zero scale.
Look for a named quadrilateral like a rhombus or parallelogram, plus two straight lines crossing inside or through it. Words like "straight line" and "collinear" point to this move.
Children mix up which angle sits opposite which once lines cross at a point away from the main shape. Trace each ray back to its two labelled ends before deciding what faces what.
