1. true or false? this shape is a quadrilateral.

1. draw a triangle that has no right angles and no equal sides.

1. circle the polygons.

Explanation:

Step1: Define quadrilateral

A quadrilateral is a 4-sided polygon.

Step2: Verify the shape

The given shape has 4 straight sides.

Step3: Define scalene obtuse/acute triangle

A triangle with no equal sides (scalene) and no right angles (all angles <90° or one >90°).

Step4: Define polygon

A polygon is a closed, flat shape with straight sides.

Step5: Identify valid polygons

Check each shape: circle (curved, not polygon), square (4 straight sides, polygon), pentagon (5 straight sides, polygon), cone (3D, not polygon), sphere (3D, not polygon).

Answer:

1. True
2. (Draw a triangle where all three sides are different lengths, and all angles are either less than 90° or one angle is greater than 90° but not equal to 90°)
3. Circle the square and the pentagon (the second and third shapes from the left)
