All About Triangles
How many degrees does a triangle have?
180 degrees
What is one example of a degree measure for an obtuse angle?
A triangle has a total of 180 degrees. A quadrilateral also has a total of 180 degrees.
No, there are 360 degrees in a quadrilateral
All triangles are acute triangles. Explain
False becausetriangles can be acute, right, or obtuse.
A triangle has one angle of 90°. What type of triangle is it ALWAYS?
Right triangle
What type of angle measures 2°?
Acute angle
A scalene triangle must have what
All sides with different lengths
Which quadrilateral has 4 equal sides but does NOT require right angles?
Rhombus
ALL parallelograms are squares
False
A triangle has angles of 45° and 60°. What is the missing angle?
75°
Scalene triangle
What word did I use in my sentence when Bimby escaped?
Adventure
A rectangle has 4 right angles. What is ALWAYS true about the opposite sides?
They are equal in length and parallel.
A square is a rectangle, rhombus, parallelogram, and a quadrilateral
True
A triangle has angles measuring 50°, 60°, and 70°. Is this possible? Explain.
Yes it is possible because they add up to 180°.
If all angles in a quadrilateral are equal, what is the measure of each angle?
90°
A trapezoid has angles measuring 70°, 110°, and 80°. What is the missing angle?
100°
A quadrilateral has both pairs of opposite sides parallel. Name the most general shape.
Parallelogram
All rectangles have 4 equal sides
False
Can a triangle have angles of 100°, 50°, and 40°? Why?
No, they add to 190°.
A triangle’s angles are in a pattern: one angle is 10° more than another, and the third is 20° more than the smallest. Find all angles
50°, 60°, 70°
If you split a quadrilateral into two triangles, what does this help prove about angle sums?
That they add to 360° (180° + 180°).
A quadrilateral has no parallel sides. What type could it be?
Irregular quadrilateral; kite
A triangle can be both right and isosceles
True
