    It's the point at which the three altitudes of a triangle intersect. Altitudes are lines which intersect with both the vertex of a triangle and the middle of the side of the triangle opposite to that vertex, as shown in this diagram:|dw:1331594454196:dw|

    So, the orthocenter would appear as so in an equilateral triangle:|dw:1331594531392:dw|

    not quite sure i agree with the definition of altitude you provided... The altitude is a line drawn from one vertex of the triangle to the line containing the opposite side that is perpendicular to the line i.e. |dw:1331594718807:dw|.

    thank you whats an isosceles triangle look like? and this is the question being asked: if <A = 94 which would be true <B = 94 or <B = 47 or AB = BC or AB = AC? Can you help

    an isosceles triangle is a triangle with two sides exactly the same length like: |dw:1331595007721:dw| the question referring to an isosceles triangle?

    well, if we're talking about an isosceles triangle, and we have one 94 degree angle, can we have another 94 degree angle? (Triangle interior angle sum th. may help here)

    it basically says, if we add together two sides, it should always be greater than the remaining side so, for your problem, we'd use it three times for each problem. We want to go through all possible combinations of sums. mathematically, we'll denote it (for three sides a, b, and c) as a + b > c, b + c > a, and a + c > b Ex) Your first part, 1.9,3.2,4 1.9 + 3.2 > 2.4, 3.2 + 4 > 1.9, and 1.9 + 4 > 3.2 These all must come out as true statements. 5.1 > 2.4 (true), 7.2 > 1.9 (true), and 5.9 > 3.2 (true!) So, this set of lengths will work for a triangle.

    hmm, that should not be 2.4, that should be 4. Sorry! It would still be true for 4, tho.

    what does it mean when it says: What is the correct relationship between the angle measures of triangle PQR? answer choices are : F. m<R < m<Q < m<P G. m<R < m<P < m<Q H. m<Q < m<P < m<R J. m<P < m<Q < m<R Side lengths are: PQ= 10 cm QR= 15 cm RP= 13 cm Can anyone explain? I am confused!

    This deals with a property of triangles that says that the largest side is across from the largest angle, and similarly the smallest side is opposite the smallest angle. If you made a diagram (not to scale)... |dw:1331599617470:dw|

    An integer is a number in the set of all whole numbers and their opposites... Like, -1, -6, 1, 5, and 0 are all integers. Integers do NOT include decimals, radicals that cannot simplify, and fractions that do not simplify.

    Yep, 7 is an integer. The counting numbers (1, 2, 3, 4, and so on), 0, and the negatives of those counting numbers (-1, -2, -3, -4, and so on) would be all integers

    suppose two lines intersect in a plane to form four angles. What do you know about the pairs of adjacent angles formed? Exsplain. I know that 1=3 and 4=2 and in the picture given 1>4 and 3>2 but I dont know how to exsplain that......

    I don't have the picture, but I imagine you got 1=3 and 2=4 from vertical angles... we're looking at adjacent angles, the angles next to each other...

    i think, rather than observing the angles themselves, you should look at each of these pairs of angles as whole units: |dw:1331601403645:dw| Specifically, the sum of the adjacent angles

    so that they equal 180?

  35. AccessDenied

    Yeah. The adjacent angles at the intersection of two lines add up to 180. The proper math term for this is that these angles are "supplementary"

    okay now i have came across a confusing one I am particually bad at story problems. Here it goes: Eric and Heather are each taking a group pf campers hiking in the woods. Eric's group leaves camp and goes 2 miles east, then turns 20 degrees south of east and goes 4 miles. Heather's group leaves camp and travels 2 miles west, then turns 30 degrees north of west and goes 4 miles. How many degrees south of east would Eric have needed to turn in order for his group and Heather's group to be the same distance from camp after the two legs of the hike?
