## Similar Polygons

Ok homeschoolers try this problem on similar polygons.

Key concepts to remember:

* know the difference between congruent and similar.

* make sure you know how set up and solve ratio and proportion problems using the cross-product.

* sometime a problem will require the use of one solution to find the next solution.

* always look at your answer and see if it makes sense compared with the picture.

* similar polygon problems are common on the SAT/ACT.

Important habits to master math:

* write out all steps

* be very neat

* use pencil not pen

* review your work as your go

* make sure you know the basics like fractions, positive and negative numbers and order of operations- these are the most common places students make mistakes

## Circles Find Angle Formed By Two Secants

Ok homeschoolers try this problem on circles involving an angle formed by two secants.

Key concepts to remember:

* know the language of circles to include secant, tangent, arcs, chords, diameter, radius and sectors.

* there are many circle angle formulas do not confuse them

* many geometry circle problems will require you to solve an algebraic equation

* make sure you use the proper units of measure

Important habits to master math:

* write out all steps

* be very neat

* use pencil not pen

* review your work as your go

* make sure you know the basics like fractions, positive and negative numbers and order of operations- these are the most common places students make mistakes

## Special Right Triangle 30-60-90

Ok homeschoolers try this problem on special right triangles with 30-60-90 degrees.

Key concepts to remember:

* master these problems as they are very common on the SAT/ACT

* you can always do these problems using the pythagorean theorem.

* you can use basic right triangle trigonometry to help you double check your work.

* make sure you know how to work with square root expressions- on some exams the answers will not be in decimals

* another special right triangle is the 45-45-90.

Important habits to master math:

* write out all steps

* be very neat

* use pencil not pen

* review your work as your go

* make sure you know the basics like fractions, positive and negative numbers and order of operations- these are the most common places students make mistakes

## Trig Functions Sine

Ok homeschoolers try this problem on right triangle trigonometry and the sine function.

Key concepts to remember:

* first make sure you know all the properties of right triangle to include the pythagorean theorem.

* you want to use a calculator for these problems

* know the phrase “SOH-CAH-TOA” it explains the ratios for sine, cosine and tangent in a right triangle

* you will need to set up a ratio equation (proportion) to solve for the missing variable

* you can always double check you solution using the pythagorean theorem.

Important habits to master math:

* be very neat

* use pencil not pen

* review your work as your go

* make sure you know the basics like fractions, positive and negative numbers and order of operations- these are the most common places students make mistakes

## Triangle Inequality

Ok homeschoolers try this problem on finding the longest and shortest sides of the triangle.

Key concepts to remember:

* this problem involves the “triangle inequality”

* the triangle inequality tell us what side is the longest and shortest in a triangle

* the triangle inequality also tells us if it’s possible to form a triangle given 3 lengths

* students want to master the triangle inequality you may see it on the SAT/ACT exam

Important habits to master math:

* be very neat

* use pencil not pen

* review your work as your go

* make sure you know the basics like fractions, positive and negative numbers and order of operations- these are the most common places students make mistakes

## Classify The Triangle

Ok homeschoolers try this problem on classifying what type of triangle this is.

Key concepts to remember:

* there are many different type of triangles

* when classifying triangles make sure you understand geometric symbols of angles, side, etc.

* once a triangle has been classified we can obtain more knowledge about it’s properties

* all triangles can be classified

Important habits to master math:

* be very neat

* use pencil not pen

* review your work as your go

* make sure you know the basics like fractions, positive and negative numbers and order of operations- these are the most common places students make mistakes
