Triangles
This type of triangle has three sides of equal length.
What type of triangle is it?
equilateral triangle
1/4+2/4=?
3/4
0.4 + 0.3 = this decimal
0.7
Which axis do you always start of from?
X-axis
An angle that measures less than 90° is called this type of angle.
Acute angle
This triangle has exactly two sides of equal length.
Isosceles triangle
5/6 − 1/3 = this fraction in simplest form.
1/2
0.6 × 0.5 = this decimal.
0.3
A graph shows temperatures of 20°, 24°, 22°, 28°, and 26°. This is the highest temperature shown.
28°
An angle that measures less than 90° is called this type of angle.
Right angle
This triangle has no sides of equal length.
Scalene triangle.
4/9 × 3/8 = this fraction in simplest form.
1/6
0.6 × 0.5 = this decimal.
4
A line graph shows a value increasing from 10 to 25 between two points. This is the amount of increase.
15
A right angle is split into two equal angles. This is the measure of each new angle.
45°
A triangle whose angle measures might be 50°, 60°, and 70° would be classified as this type based on its angles.
Acute triangle
5/12 ÷ 10/27 = this fraction in simplest form.
9/8
0.125 × 8 = this number.
1
A line graph shows temperatures over 5 days: 60°, 64°, 68°, 72°, 76°. How much did the temperature increase from Day 2 to Day 5?
12°
Two angles form a straight line. One angle measures 68°. What is the measure of the other angle?
112°
According to the Pythagorean Theorem, if the square of the longest side equals the sum of the squares of the other two sides, the triangle is this type.
Right triangle
3/10 + 7/15 = this fraction in simplest form.
23/30
A student calculates 12.48÷0.24. The quotient is this number.
52
A line graph shows values: 40, 35, 27, 16, 2. This is how much the value decreases from the first point to the last point.
38
Two lines meet to form an angle. One line points straight right (0° direction). The second line is rotated so the angle between them is 125°. If you draw a straight line opposite the first line, what is the measure of the supplementary angle to 125°?
55°
