What three pieces of information (SAS) do you need to construct a triangle using two sides and one angle?
Show answer
Two side lengths and the angle between them.
What three pieces of information (ASA) do you need to construct a triangle using two angles and one side?
Show answer
One side length (usually the base) and two angles at the ends of that side.
What three pieces of information (SSS) do you need to construct a triangle using three sides?
Show answer
All three side lengths.
A triangle with all three sides equal is called an ? triangle.
Show answer
equilateral
How many different isosceles triangles can be constructed with a given angle measurement?
Show answer
More than one (at least two), because the given angle could be the vertex angle or one of the base angles.
A triangle with two sides of equal length is called an ? triangle.
Show answer
isosceles
When using a scale of 1cm = 200m in a triangle construction, how would you represent 1km?
Show answer
5cm (because 1km = 1000m, and 1000m ÷ 200m/cm = 5cm).
