- Obtuse = one side is more than 90 degrees
- Acute = all sides are less than 90 degrees
- Isosceles = two sides are of the same length
- Equilateral triangle: all angles are of same measure (60)
- Scalene: all sides are of different lengths
- Right Triangle: One of the angles equals 90 degrees.
Since it takes her 2 1/2 miles to get to the aquarium from her hotel, you need to subtract the various distances from this value in order to find how long it took Clara to walk the rest of the way to the aquarium.
2 1/2 - (1/4+1 3/4)= 2 1/2 - 2= 1/2
Clara must walk 1/2 a mile to get the rest of the way to the aquarium.
Answer:
123
Step-by-step explanation:
012+121
Difference-of-Squares Formula:
For a difference of squares a2 – b2, the factorization is:
(a – b)(a + b)
you have to break the shape into parts and find the are of each part. so 2 times 2 to find the area of the square part and 2 times 1 times one half to find the area of the triangle part. then you add them together to get the total area
