All Tasks - Asymptote

Your learning graph should look something like this by now. The score bar above shows how many of the possible points you have achieved so far. The points from the challenge tasks are displayed separately from those from the main and support tasks, since support tasks shall only compensate for the lost points from main tasks. Tasks of the type "information station" like this one do not provide any points since no solution is entered.

The image shows two parallel straight lines intersected by a third line. Fill in the blanks below in order to determine the size of angle $\beta$.

The image shows two pairs of parallel lines intersected by a fifth line. The size of angle $\alpha$ is 45°, $\beta$ is 65°. Determine the size (as numbers, without °) of the two purple angles and complete the checkboxes below.

Below, select all true statements about the circle in the image. The unit of length is centimeters.

Given the quadratic function $f(x)= x^2-4x-5$. Determine all its zeros. The task type "set" does not take into account the order in which the answers are given (just like a set is commutative). Insert all results in the box below.

This task type enables the user to insert a single fraction, either simple or mixed. Calculate the sum of $\frac{1}{5}$ and $\frac{14}{15}$. Divide the result by $\frac{3}{5}$ and finally subtract $\frac{11}{18}$. Insert the resulting mixed fraction below.
