Review Cycle 4

How can you find area and perimeter of a figure like this?

How can you make these conversions?

Now you know, find the answer for this one in your Math journal. You will have to type it in the next slide!

Write the answer for the previous question!

What is the best way to find elapsed time?

Now you know! Find the answer for this one in your Math journal! You will have to type it in the next slide.

Write the answer for the last question:

Can you remember what parallel, perpendicular and intersecting are?

Too many lines! Read the angles correctly

How to measure angles (easy)

• Use 90 degrees as a reference!

• Is it an easy one? If one of lines is in the 0 degrees, just read the other line! Look at the example in the next slide

Now you can find this one! Write the answer in the next slide. Ready?

Write the answer for the last question

How to measure angles (intermediate)

• What if there's many angles? It might look a bit messy.

• No worries! Just find the right lines to find the right angle. Look at the next example

How to measure angles (hard)

• Ok, here we go...what if the sides are not in the 0 degrees mark?

• If both sides are in numbers different than zero then...

• Just subtract the sides! Look at the next slide

So, what about this one? Find out the answer and get ready. You will have to type it in the next slide!

Write the answer for the last question

How to measure angles (expert)

• What if we have polygons instead of just lines?

• Look at the next slide!

How can we solve this? A million Faber bucks to whoever can explain this

Speaking of polygons...

What is a polygon?

A polygon is a figure with at least three sides and angles.

Triangles

Quadrilaterals

Pentagons

Hexagons

Heptagons

...

Quadrilaterals are tricky!

We know squares, rectangles, rhombuses...but two are confusing. Write these in your notes!

> Parallelogram: Two pairs of parallel lines

> Trapezoid: One pair of parallel lines
