Triangles
Name the triangle that has ALL EQUAL SIDES.
Equilateral Triangle.
A tool to measure angles in math is known as ________.
a Protractor
A special type of rhombus with four 90 degree angles is also known as this ________________.
a SQUARE
Parallel lines mean lines that will eventually meet up and intersect.
FALSE. Parallel lines are lines that will never meet.
Parallelograms are not quadrilaterals.
FALSE! All parallelograms are 4 sided.
Name the triangle that has NO EQUAL sides.
SCALENE triangle.
Name the triangle with an angle greater than 90 degrees.
OBTUSE triangle.
True/False. A pentagon has 5 sides. A hexagon has 6 sides. An octagon has 8 sides.
TRUE!
the large angle of an isosceles triangle measures 100 degrees. The measurements of the other two angles are _______________.
40 degrees each since an isosceles triangle has two congruent angles
Parallelograms have four sides and four angles.
TRUE!
Name the triangle that has TWO sides that are equal.
ISOSCELES triangle.
Name the triangle with an angle that measures 90 degrees
Right angle triangle
True/False Polygons have at least two sides or more.
FALSE. Polygons must have at least three sides.
Same
Parallelograms have 2 pairs of parallel sides.
TRUE! If there is ONE pair of parallel lines and 4 sides this shape is called:
Is it possible to construct a triangle with all OBTUSE angles? Why or why not?
Why can't triangles have three 90 degree angles?
The sides won't come together to form a triangle. they'll measure more than 180 degrees when combined and the combined measurements of a triangle always measure up to 180 degrees
A shape with four different length sides and no parallel sides is known as an _______________.
irregular quadrilateral
Colour, size, and temperature are GEOMETRIC properties.
FALSE - they are physical properties.
Name at least 3 different shapes that are parallelograms.
Squares, Rhombus', Rectangles, and Parallelograms are all types of parallelograms.
60 degrees
a triangle with all the same angles and sides
Equilateral Triangle.
What makes a trapezoid different from a parallelogram?
a trapezoid always has one set of parallel lines
Lines can be vertical, horizontal, and diagonal.
TRUE! Draw them now in the air.
Squares and Rectangles are special types of parallelograms. What makes them different from a regular parallelogram?
They have four right angles. Regular parallelograms have 2 acute angles and 2 obtuse angles.
