1. Identify the geometric figures and the labeled angles in the image. 2. What is the sum of angles in a triangle?

Geometric Figures and Angles:

The image displays several geometric figures, including parallel lines intersected by a transversal, right-angled triangles, and a triangle inscribed in a circle.

• Figure 1 (Top Left): Two parallel lines intersected by a transversal, with angles labeled 1 and 2 (alternate interior angles).
• Figure 2 (Top Right): An angle divided into two parts, labeled 1 and 2.
• Figure 3 (Middle Left): Two parallel lines intersected by a transversal, with lines labeled 'a' and 'b'. Angles are labeled 1 and 2.
• Figure 4 (Middle Right): An isosceles triangle with sides marked as equal. Angles are labeled 1 and 2.
• Figure 5 (Bottom Left, top): A right-angled triangle with angles labeled 1 and 2, and a right angle symbol.
• Figure 6 (Middle Right): An isosceles triangle with angles labeled 1 and 2.
• Figure 7 (Bottom Left, bottom): A right-angled triangle with one angle given as 30 degrees, and other angles marked with a question mark.
• Figure 8 (Bottom Right): A triangle inscribed in a circle with center O. Angles are labeled 1 and 2.

Sum of Angles in a Triangle:

The sum of the interior angles of any triangle is always 180 degrees.

Answer: The sum of angles in a triangle is 180 degrees.
