Unit 4, Lesson 3
Half an Equilateral Triangle
Geometry
Practice
Problem 1
Select all statements that are true about equilateral triangle \(ABC\).
Triangle A B C. Point D lies on B C. Side A C is labeled 6. A dotted line is drawn from point A to point D with a right angle symbol as it hits point D. The dotted line is labeled x. Angles B and C each have an arc with a single tick mark.
Angles \(B\) and \(C\) are 60 degrees.
\(x = 3\sqrt{3}\)
\(x = 6\sqrt{3}\)
Triangle \(ABD\) is congruent to triangle \(ACD\).
Both \(BD\) and \(CD\) are 3 units long.
