What is the probability of catching a certain color fish?

Put your knowledge of probability to work.

Keep track of results of spinner with equal likely outcomes of successfully landing on purple, green, red, orange, or yellow.

Time to comment.

Suppose you toss a quarter once. What is the probability of the quarter landing heads up? There are two possible outcomes in this situation, heads or tails. Since only one of the two outcomes will give us heads, the probability of the quarter landing heads up is 1/2. What is the probability of obtaining one head if you toss two quarters? Carefully think about the number of possible outcomes.

Let's continue with our project - Classifying Triangles

We can classify triangles by sides or angles.

Begin by finding the area of a triangle.

Side lengths

Equilateral all sides are the same length.

Isosceles. two sides are the same length.

Scalene: no sides are the same length.

Angles

Acute triangle: has all angles less than 90 deg.

Right triangle: has one 90 deg angle.

Obtuse triangle: has an angle greater than 90 deg.

Try Activity One

After you finished the matching watch this video on triangles.
