Acute angles measure less than 90 degrees.

The symbol for perpendicular is a right angle symbol, which looks like a small square placed at the vertex of an upside-down capital letter "T". This symbol is commonly used in geometry to represent two lines or line segments that intersect at a 90-degree angle. Therefore, the given statement is true.

The vertex is point D.

A diagonal is a line segment that connects two nonconsecutive vertices in a polygon. This means that it does not connect two adjacent vertices. Therefore, the statement that a diagonal is a line segment in a polygon connecting any two nonconsecutive vertices is true.

A scalene triangle is a type of triangle where all three sides have different lengths. This means that no two sides of the triangle are the same length. Therefore, the statement "A scalene triangle is a triangle with no two sides the same length" is true.

The statement is true because the length of segment PQ can indeed be represented as PQ. In geometry, segments are typically labeled using two points, in this case, P and Q. The length of a segment is denoted by the distance between these two points, which can be represented as PQ.

It is written as

Vertical angles are formed when two lines intersect. In this case, the question does not provide any information about lines intersecting. Therefore, we cannot determine if the angles are vertical or not. Hence, the correct answer is False.

They are supplementary.
