From the image you uploaded, I can see that there are multiple problems involving triangles, with different labels, side lengths, and angle measurements. Let's go through the general instructions visible and address each problem step-by-step.

Problem Breakdown:

1. Question 1 (a-c) involves identifying missing side lengths, angles, or labeling for three triangles.
2. Question 2 (a-b) involves determining the spaces between vertices or using the Pythagorean theorem.

I'll work through what is clearly visible and provide guidance on solving them:

For Question 1:

The task seems to require filling in missing information for angles or sides.

• Triangle (a): The angles are marked with a small circle, possibly indicating right angles or angles that can be determined by angle sum property (sum of angles in a triangle = 180°).

• Triangle (b): This triangle has a longer side, and there might be a missing length.

• Triangle (c): Similar to the previous one but rotated, again with marked angles and sides.

For Question 2:

The task is possibly related to labeling or calculating distances between the points or determining if the triangles follow Pythagoras' theorem.

Guidance:

• Use of the Pythagorean theorem: If the triangles are right-angled, you can apply the formula $a^2 + b^2 = c^2$, where $c$ is the hypotenuse (longest side).

• Sum of Angles in a Triangle: Always 180°, so if you know two angles, subtract their sum from 180° to find the third.

Tip: For triangle problems, always double-check if any sides or angles are missing, and use basic properties like angle sum or the Pythagorean theorem to complete them.
