wheel of fortune

Math shapes

I challenge you! What do you know about regular and irregular polygons, triangles, quadrilaterals and parallelograms, circumferences and circles?

Spin

the wheel!

FOR 25 POINTS

It has 2 sides that measure 11cm and another of 9cm.

CORRECT!

And if you'd like to take a look at our triangle, click below.

25 POINTS

Math shapes

Isosceles triangle

FOR 100 POINTS

Think carefully and respond:

Can a triangle be a rectangle and an equilateral?

Yes

Yes, because it has an acute angle.

No

125 POINTS

Math shapes

As you know, all the internal angles of an equilateral triangle are the same,

and should add up to 180°, so it could never have a 90° angle.

FOR 75 POINTS

It has 4 sides that are 8cm in length, 2 120° angles and 2 60° angles. What type of parallelogram is it?

rectangle

rhomboid

rhombus

125 POINTS

Math shapes

CORRECT!

And just to triple check, click on the eye below to see the characteristics of a rhombus.

200 POINTS

Math shapes

The rhombus: Its 4 sides are the same length. Opposite angles are the same.

This parallelogram is a rhombus for sure!

FOR 250 POINTS

Think carefully:

Yes, because they have 4 sides.

No, because its sides are not necesarily parallel.

Sí, because its angles add up to 360°.

200 POINTS

Math shapes

CORRECT!

And to get rid of any doubts, what is a good example of a quadrilateral that's not a parallelogram?

450 POINTS

Math shapes

Of course!

A trapezoid

Asymmetrical trapezoid Symmetrical trapezoid

FOR 50 POINTS

What is the radius of a circumference?

It is the segment joining the center with any point on the circumference.

It is the segment that joins 2 points of the circumference and passes through the center.

It is the part of the circumference between 2 points of the circumference.

FOR 250 POINTS

What's the difference between a square and a rhombus?

There is no difference, both are quadrilaterals.

In a square all the angles measure 90° and in a rhombus they do not.

A square has 2 parallel sides and a rhombus does not.

CORRECT!

So, what do you think, is a square a rhombus? Maybe the video below will help us answer the question for once and for all!

What is the diameter of a circumference?

It is the segment that joins 2 points of the circumference.

It is the segment that joins 2 points of the circumference and passes through the center.

It is the segment that joins the center with any point of the circumference.
