Similarity of triangles
Click here to see the code
General objective: determine the length of an unknown side in a triangle by triangle similarity with other
Specific objectives:
Make sure the relationship between the ribs similar, the triangles.
Identify the ratios between similar triangles.
Scientific material: similar Almthelthan If Odilallma Zoaehma proportionate and disproportionate in front of the ribs are identical. And the percentage of similarity is the ratio between the longitudinal ribs of the opposite angles are the same.
Explain the code:
Move the capital triangles abc and d WSF is controlled in the dimensions of two triangles, then the code directly Blaejad percentage similarity, noting that the code in the process of conclusion at the bottom of the code composition ratio between each rib and the rib corresponding in the Triangle the second, note the following figure:
Example:
· Almthelthan (CMM), (d P r) The two paintings are similar:
· Be based on the measurements of angles of the triangle (CMM) match the corresponding angles in the triangle (d P r).
· Based on the ratio between the sides of the triangle (CMM) is equal to the ratio between the sides of the triangle (d P r). Drawing s <(a d b) = s <(l and m).
· And thus a ÷ c = b d P a r d ÷
· To ensure that we create that ratio, we find the following
The ratio between the Dhalaan · [c a], [P d] = 4 ÷ 6 is equal to the ratio between the Dhalaan [A B], [Y d] = 5 ÷ 8
