## Which point represents the vertex of the marked angle?

A. a B. e

C. c

D. b

E

Step-by-step explanation:

Given : ∠AEC

To Find: Which point represents the vertex of the marked angle?

Solution:

Vertex is a corner or a point where lines meet.

Arms of ∠AEC are AE and EC

So, these arms meet at point E

According to the definition of vertex

E is the vertex of ∠AEC

Hence E point represents the vertex of the marked angle

Lines and Angles | Properties and Examples – An angle is a space or the gap formed between two lines that meet at a point and the meeting point is called the Vertex. The two lines originating from the same point are called the arms of the angle. The Angles are classified into different types such as Acute angle, Right angle, Obtuse angle, Straight angle, Reflex angle, and Full angleWhich point represents the vertex of the marked angle? Watch. 1 answer · 0 watching · 23 viewsThe lower right angle is marked as 55 degrees. The angle at the vertex of the inverted triangle at the top is marked as x degrees. The angle at the vertex of the bottom triangle is marked as y degrees. 45 80 55 100 19. Which point in the figure shown is the vertex of an angle? A. B B. D C. C D. A In the image below which point is the vertex of

Which point represents the vertex of the marked angle? – The angle symbol, followed by three points that define the angle, with the middle letter being the vertex, and the other two on the legs. So in the figure above the angle would be ∠ABC or ∠CBA. So long as the vertex is the middle letter, the order is not important. For example '∠ABC' would be read as 'the angle ABC'.No matter how many angles are there in a diagram, each angle has its own unique name. We use the symbol ' ∠ ' followed by the name to represent an angle. The below links have more on how you can label an angle and in how many different ways you can accomplish this task. 1. Label an angle using the vertex and a point from each arm. 2.Any angle with a measure of less than 180º has an interior and exterior, as shown below. Slide 32 / 190 Naming Angles · By its vertex (B in the below example) · By a point on one leg, its vertex and a point on the other leg (either ABC or CBA in the below example) · Or by a number or a symbol placed inside the angle (e.g.

Point \_\_\_is the vertex of the angle marked in the figure. – The line perpendicular to the directrix and passing through the focus (that is, the line that splits the parabola through the middle) is called the " axis of symmetry ". The point where the parabola intersects its axis of symmetry is called the " vertex " and is the point where the parabola is most sharply curved.The meeting point of two straight lines is called as vertex. The word vertex is mostly used to denote the corner point of the polygon. Equilateral triangle is one type of triangle, which all three sides are equal in length and its all three interior angles are 600 and the sum of interior angle is 1800.Question: Which point represents the vertex of the marked angle?
