Question

ABC is an isoceles triangle wiith AB=AC. prove that the altitudes BE and CF of the triangle are equal

Answer 1

Hope it would be your answer and it is right

Step-by-step explanation:

we know that AB=CA

now in triangles BFC and EBC

angle B=angle C (property of isosceles triangle) .... (1)

side BC = side BC (common) ..... (2)

angle F= angle E (as both are given 90°) ........(3)

by (1) , (2), (3)

it is proven that triangle BFC is congruent to triangle EBC by SAS property.

Hence it is proven that side BF= side EC by congruent part of congruent triangle (CPCT)

Answer 2

Answer:

the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
