Question

Construct Triangle LMN if LN=4cm , angle MLN=39 degrees and angle MNL=80 degrees. What type of triangle does this cręate?

A. equiangular
B. right
C. obtuse
D. acute

Answer 1

To construct Triangle LMN, start by drawing LN = 4cm as the base. From point L, draw a line segment LM at an angle of 39 degrees, and from point N, draw MN at an angle of 80 degrees. This creates an obtuse triangle.

Step-by-step explanation:

To construct Triangle LMN, we can start by drawing LN = 4cm as the base of the triangle. From point L, we can draw a line segment LM at an angle of 39 degrees. Then, from point N, we can draw a line segment MN at an angle of 80 degrees. The triangle created by these constructions will be an obtuse triangle because it has one angle greater than 90 degrees.
