Understand the Problem
The question contains a series of multiple-choice questions focused on geometry concepts such as properties of lines, shapes, and angles, as well as some completion statements about triangles and polygons.
Answer
1. Point, 2. Rhombus, 3. 40°, 4. Zero, 5. 70°, 6. Error, Q2: 1. 180°, 2. Equal, 3. 135°, 4. 110°.
The answers are: 1. A point, 2. A rhombus, 3. 40°, 4. Zero, 5. 70°, 6. Error possibly, 7. Check sums, Q2: 1. 180°, 2. Equal, 3. 135°, 4. 110°.

The answers are: 1. A point, 2. A rhombus, 3. 40°, 4. Zero, 5. 70°, 6. Error possibly, 7. Check sums, Q2: 1. 180°, 2. Equal, 3. 135°, 4. 110°.
More Information
For question 6, there seems to be a logical error, as having ∠A = 90° and ∠B = 90° leaves no room for ∠C.
Tips
Ensure to check if angles given logically add up to 180° in a triangle.
