What three pieces of information are needed to construct a triangle using the SAS (Side-Angle-Side) method?
Show answer
Two sides and the included angle between them.
What three pieces of information are needed to construct a triangle using the ASA (Angle-Side-Angle) method?
Show answer
Two angles and the included side between them.
What three pieces of information are needed to construct a triangle using the SSS (Side-Side-Side) method?
Show answer
All three side lengths.
A triangle with all three sides equal is called an ? triangle.
Show answer
equilateral
A triangle with two equal sides is called an ? triangle.
Show answer
isosceles
In an equilateral triangle with side length 6 cm, all three angles measure what?
Show answer
60°. All angles in an equilateral triangle are equal, and since angles in a triangle sum to 180°, each is 60°.
When using a scale drawing where 1 cm = 200 m, how many centimeters represent 1 km?
Show answer
5 cm. Since 1 km = 1000 m, and 200 m = 1 cm, then 1000 m ÷ 200 = 5 cm.
What tool is typically used to construct a triangle when all three side lengths are known?
Show answer
A compass (or pair of compasses). It is used to draw arcs from two vertices to find the third vertex where the arcs intersect.
